DevExpress13.2.9 控件使用经验总结
一.换肤功能
1. 添加 DevExpress.OfficeSkins 和 DevExpress.BonusSkins 两个引用
2. 皮肤注册
DevExpress.UserSkins.BonusSkins.Register();
DevExpress.Skins.SkinManager.EnableFormSkins();
3. 加载皮肤列表，调用 SkinTools.LoadSkinList 函数
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows.Forms; using psi.Common; using psi.Interfaces; using DevExpress.Skins; using DevExpress.LookAndFeel; /************************************************************************* * 程序说明: 设置皮肤工具 **************************************************************************/ namespace psi.Library { /// <summary> /// 设置皮肤工具 /// </summary> public class SkinTools { private static ToolStripMenuItem _CurrentSkinList = null; /// <summary> /// 加载皮肤列表 /// </summary> public static void LoadSkinList(ToolStripMenuItem owner) { _CurrentSkinList = owner; int skinCount = DevExpress.Skins.SkinManager.Default.Skins.Count; ToolStripItem[] itemArr = new ToolStripItem[skinCount]; int index = 0; foreach (DevExpress.Skins.SkinContainer skin in DevExpress.Skins.SkinManager.Default.Skins) { ToolStripMenuItem item = new ToolStripMenuItem(); item.Text = skin.SkinName; item.Name = skin.SkinName; item.Checked = skin.SkinName == SystemConfig.CurrentConfig.SkinName; item.Click += new System.EventHandler(OnSetSkinClick); itemArr[index] = item; ++index; } owner.DropDownItems.AddRange(itemArr); } /// <summary> /// 设置皮肤 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private static void OnSetSkinClick(object sender, EventArgs e) { ToolStripMenuItem clickItem = sender as ToolStripMenuItem; SetSkin(clickItem.Name); if (_CurrentSkinList != null) { foreach (ToolStripMenuItem item in _CurrentSkinList.DropDownItems) { item.Checked = false; } } clickItem.Checked = true; } public static void SetSkin(string skinName) { //设置所有窗体的皮肤 for (int i = 0; i < Application.OpenForms.Count - 1; i++) { Form form = Application.OpenForms[i]; if (form is IFormBase) (form as IFormBase).SetSkin(skinName); } } } }
4. 效果如下图
二. Grid 显示行号以及设置行号列名称
1. 添加 GridView 方法 CustomDrawRowIndicator
/// <summary> /// 显示行号和设置行号列头部的字符 /// </summary> private void gvSummary_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e) { if (e.Info.Kind == DevExpress.Utils.Drawing.IndicatorKind.Header) { e.Info.DisplayText = "行号"; } e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center; if (e.Info.IsRowIndicator && e.RowHandle >= 0) { e.Info.DisplayText = Convert.ToString(e.RowHandle + 1); } }
2. 效果如下图
三. Grid 下添加固定合计行
1. 继承 GridView ，自定义表格 GridViewSummary，改变Grid父级控制器
using System; using System.Collections.Generic; using System.ComponentModel; using System.Diagnostics; using System.Linq; using System.Text; using DevExpress.XtraGrid.Views.Grid; using DevExpress.XtraGrid.Columns; using System.Windows.Forms; using DevExpress.Skins; using DevExpress.LookAndFeel; using System.Drawing; using DevExpress.XtraGrid; using System.Collections; namespace psi.UserControls.SummaryDataGrid { public partial class GridViewSummary : GridView { #region Browsable properties /// <summary> /// 是否显示合计行的头部 /// </summary> private bool displaySumRowHeader;

this.parentPanel.BorderStyle = System.Windows.Forms.BorderStyle.FixedSingle; this.parentPanel.Dock = DockStyle.Top; Size panelSize = new Size(); panelSize.Height = this.GridControl.Height + summaryControl.InitialHeight; this.parentPanel.Size = panelSize; summaryControl.Dock = DockStyle.Bottom; int controlIdx = parent.Controls.GetChildIndex(this.GridControl); parent.Controls.Remove(this.GridControl); this.GridControl.Location = new Point(0, 0); this.GridControl.SizeChanged += delegate(object sender, EventArgs e) { GridControl obj = (GridControl)sender; if (obj.Width != gridOldWidth) { AdjustColumnWidth(); summaryControl.resizeSumBoxes(); gridOldWidth = obj.Width; } }; this.parentPanel.Controls.Add(this.GridControl); this.parentPanel.Controls.Add(summaryControl); this.parentPanel.SizeChanged += delegate(object sender, EventArgs e) { if (Program.HomeForm.WindowState != FormWindowState.Minimized) { Panel obj = (Panel)sender; if (obj.Width != 0 && obj.Width != GridControl.Width) { gridOldWidth = GridControl.Width; GridControl.Width = obj.Width; } } }; parent.Controls.Add(parentPanel); parent.Controls.SetChildIndex(parentPanel, controlIdx); } } /// <summary> /// 取得所有显示的列 /// </summary> public List<GridColumn> DisaplyColumns { get { List<GridColumn> result = new List<GridColumn>(); GridColumnCollection columns = this.Columns; if (columns == null) return result; foreach (GridColumn column in columns) { if (column.Visible) result.Add(column); } return result; } } public delegate void BeforeEndInitHandler(); public event BeforeEndInitHandler BeforeEndInit; public override void EndInit() { if (BeforeEndInit != null) BeforeEndInit(); ChangeSummarySkin(); ChangeParent(); summaryControl.reCreateSumBoxes(); } protected override void OnLookAndFeelChanged() { base.OnLookAndFeelChanged(); ChangeSummarySkin(); summaryControl.reCreateSumBoxes(); } private int gridOldWidth; /// 手动处理列宽度 public delegate void HandlerColumnWidth(GridColumn column, int maxWidth); public event HandlerColumnWidth ColumnWidthHandler; /// 不进行宽度调整的列 public delegate List<GridColumn> ExcludeAdjustWidthColumns(); public event ExcludeAdjustWidthColumns ExcludeAdjustColumns; /// <summary> /// 调整列宽度 /// </summary> public void AdjustColumnWidth() { Control parent = this.GridControl.Parent; if (!DesignMode && parent != null) { int gridWidth = this.GridControl.Width; int columnsWidth = this.IndicatorWidth + 18; int count = 0; foreach (GridColumn column in DisaplyColumns) { if (ExcludeAdjustColumns != null) { List<GridColumn> excludeColumns = ExcludeAdjustColumns(); if (excludeColumns != null && excludeColumns.Contains(column)) { continue; } } count++; column.Width = (column.Width * gridWidth) / gridOldWidth; if (ColumnWidthHandler != null) ColumnWidthHandler(column, gridWidth - columnsWidth); columnsWidth += column.Width; } } } /// <summary> /// 删除全部行 /// </summary> public void ClearRows() { bool _mutilSelected = this.OptionsSelection.MultiSelect;//获取当前是否可以多选 if (!_mutilSelected) this.OptionsSelection.MultiSelect = true; this.SelectAll(); this.DeleteSelectedRows(); this.OptionsSelection.MultiSelect = _mutilSelected;//还原之前是否可以多选状态 } } }
2. GridViewSummary 所属的父级控制器，创建合计行
using System; using System.Collections.Generic; using System.ComponentModel; using System.Diagnostics; using System.Linq; using System.Text; using System.Windows.Forms; using System.Collections; using DevExpress.XtraGrid; using System.Drawing; using DevExpress.XtraGrid.Views.Grid; using DevExpress.XtraGrid.Views.Base; using DevExpress.XtraGrid.Columns; using DevExpress.Skins; using DevExpress.LookAndFeel; using System.Data; namespace psi.UserControls.SummaryDataGrid { public class SummaryControlContainer : UserControl { #region Declare variables private Hashtable sumBoxHash; private GridViewSummary gridViewSummary; private Label sumRowHeaderLabel; private int initialHeight; public int InitialHeight { get { return initialHeight; } set { initialHeight = value; } } public Hashtable SumBoxHash { get { return this.sumBoxHash; } } #endregion #region Constructors public SummaryControlContainer(GridViewSummary gridViewSummary) { if (gridViewSummary == null) throw new Exception("GridViewSummary is null!"); this.gridViewSummary = gridViewSummary; sumBoxHash = new Hashtable(); sumRowHeaderLabel = new Label(); } #endregion #region Functions /// <summary> /// Checks if passed object is of type of integer /// </summary> /// <param name="o">object</param> /// <returns>true/ false</returns> protected bool IsInteger(object o) { if (o is Int64) return true; if (o is Int32) return true; if (o is Int16) return true; return false; } /// <summary> /// Checks if passed object is of type of decimal/ double /// </summary> /// <param name="o">object</param> /// <returns>true/ false</returns> protected bool IsDecimal(object o) { if (o is Decimal) return true; if (o is Single) return true; if (o is Double) return true; return false; } /// <summary> /// Create summary boxes for each Column of the DataGridView /// </summary> public void reCreateSumBoxes() { ReadOnlyTextBox sumBox; Skin GridSkin = GridSkins.GetSkin(UserLookAndFeel.Default.ActiveLookAndFeel); Skin CommonSkin = CommonSkins.GetSkin(UserLookAndFeel.Default.ActiveLookAndFeel); foreach (Control control in sumBoxHash.Values) { this.Controls.Remove(control); } int iCnt = 0; List<GridColumn> gridColumns = this.gridViewSummary.DisaplyColumns; foreach (GridColumn gridColumn in gridColumns) { sumBox = new ReadOnlyTextBox(); sumBox.Top = 0; sumBox.Height = this.initialHeight; sumBox.BorderColor = GridSkin[GridSkins.SkinGridLine].Color.BackColor; sumBox.Font = this.gridViewSummary.GridControl.Font; sumBox.ForeColor = this.gridViewSummary.GridControl.ForeColor; iCnt++; bool isMergeColumn = false; foreach (MergeColumn mergeColumn in this.gridViewSummary.MergeColumns) { if (gridColumn.VisibleIndex >= mergeColumn.StartIndex && gridColumn.VisibleIndex <= mergeColumn.EndIndex) { isMergeColumn = true; if (gridColumn.VisibleIndex == mergeColumn.StartIndex) { if (gridColumns.Count == iCnt + (mergeColumn.EndIndex - mergeColumn.StartIndex + 1)) { sumBox.IsLastColumn = true; } if (sumBoxHash.ContainsKey(mergeColumn.ColumnName)) { ReadOnlyTextBox textBox = (ReadOnlyTextBox)sumBoxHash[mergeColumn.ColumnName]; sumBox.Text = textBox.Text; sumBoxHash.Remove(mergeColumn.ColumnName); } sumBoxHash.Add(mergeColumn.ColumnName, sumBox); this.Controls.Add(sumBox); } break; } } if (isMergeColumn) continue; if (gridColumns.Count == iCnt) sumBox.IsLastColumn = true; if(sumBoxHash.ContainsKey(gridColumn.Name)) { ReadOnlyTextBox textBox = (ReadOnlyTextBox)sumBoxHash[gridColumn.Name]; sumBox.Text = textBox.Text; sumBoxHash.Remove(gridColumn.Name); } sumBoxHash.Add(gridColumn.Name, sumBox); if (gridViewSummary.SummaryColumns != null && gridViewSummary.SummaryColumns.Length > 0) { for (int iCntX = 0; iCntX < gridViewSummary.SummaryColumns.Length; iCntX++) { if (gridViewSummary.SummaryColumns[iCntX] == gridColumn.Name) { sumBox.TextAlign = TextHelper.TranslateGridColumnAligment(gridColumn.AppearanceCell.TextOptions.HAlignment); sumBox.IsSummary = true; sumBox.FormatString = gridColumn.DisplayFormat.FormatString; if (gridColumn.ColumnType == typeof(System.Int32) || gridColumn.ColumnType == typeof(System.Int16) || gridColumn.ColumnType == typeof(System.Int64) || gridColumn.ColumnType == typeof(System.Single) || gridColumn.ColumnType == typeof(System.Double) || gridColumn.ColumnType == typeof(System.Single) || gridColumn.ColumnType == typeof(System.Decimal)) sumBox.Tag = System.Activator.CreateInstance(gridColumn.ColumnType); break; } } } this.Controls.Add(sumBox); } if (gridViewSummary.DisplaySumRowHeader) { sumRowHeaderLabel.Width = this.gridViewSummary.IndicatorWidth; sumRowHeaderLabel.Font = new Font(this.gridViewSummary.GridControl.Font, this.gridViewSummary.SumRowHeaderTextBold ?

3. 合计行的单元格对象
using System; using System.Collections.Generic; using System.ComponentModel; using System.Drawing; using System.Data; using System.Linq; using System.Text; using System.Windows.Forms; using System.Text.RegularExpressions; using psi.Common; namespace psi.UserControls.SummaryDataGrid { public partial class ReadOnlyTextBox : UserControl { StringFormat format; public event EventHandler TextChanged; public ReadOnlyTextBox() { InitializeComponent(); format = new StringFormat(StringFormatFlags.NoWrap | StringFormatFlags.FitBlackBox | StringFormatFlags.MeasureTrailingSpaces); format.LineAlignment = StringAlignment.Center; this.Height = 10; this.Width = 10; this.Padding = new Padding(2); } private Color borderColor = Color.Black; private bool isSummary; public bool IsSummary { get { return isSummary; } set { isSummary = value; } } private bool isLastColumn; public bool IsLastColumn { get { return isLastColumn; } set { isLastColumn = value; } } private string formatString; public string FormatString { get { return formatString; } set { formatString = value; } } private HorizontalAlignment textAlign = HorizontalAlignment.Left; [DefaultValue(HorizontalAlignment.Left)] public HorizontalAlignment TextAlign { get { return textAlign; } set { textAlign = value; setFormatFlags(); } } private StringTrimming trimming = StringTrimming.None; [DefaultValue(StringTrimming.None)] public StringTrimming Trimming { get { return trimming; } set { trimming = value; setFormatFlags(); } } private void setFormatFlags() { format.Alignment = TextHelper.TranslateAligment(TextAlign); format.Trimming = trimming; } public Color BorderColor { get { return borderColor; } set { borderColor = value; } } protected override void OnPaint(PaintEventArgs e) { int subWidth = 0; Rectangle textBounds; if (!string.IsNullOrEmpty(formatString) && !string.IsNullOrEmpty(Text)) { decimal num = Convert.ToDecimal(ConvertEx.replaceCurrency(Text)); if (Text.Contains('%')) num = decimal.Divide(num, 100); Text = String.Format("{0:" + formatString + "}", num); } textBounds = new Rectangle(this.ClientRectangle.X, this.ClientRectangle.Y, this.ClientRectangle.Width, this.ClientRectangle.Height); using (Pen pen = new Pen(borderColor)) { if (isLastColumn) subWidth = 1; e.Graphics.FillRectangle(new SolidBrush(this.BackColor), this.ClientRectangle); e.Graphics.DrawRectangle(pen, this.ClientRectangle.X, this.ClientRectangle.Y, this.ClientRectangle.Width - subWidth, this.ClientRectangle.Height); e.Graphics.DrawString(Text, Font, new SolidBrush(ForeColor), textBounds, format); } } protected override void OnTextChanged(EventArgs e) { base.OnTextChanged(e); if (TextChanged != null) TextChanged(this, e); } } }
4. 使用自定义表格 GridViewSummary，效果如下
四. Grid 自定义绘制操作列头
1. 创建 修改列(operate_modify)、删除列(operate_del)
2. 添加 GridView 方法 CustomDrawColumnHeader，绘制表头
/// <summary> /// 自定义绘制操作列表头 /// </summary> private void gvDetail_CustomDrawColumnHeader(object sender, DevExpress.XtraGrid.Views.Grid.ColumnHeaderCustomDrawEventArgs e) { if(e.Column != null) { if (e.Column == operate_modify) { e.Info.InnerElements.Clear(); e.Painter.DrawObject(e.Info); e.Handled = true; int delColumnWidth = operate_del.VisibleWidth; e.Graphics.FillRectangle(new SolidBrush(e.Info.Appearance.BackColor), new Rectangle(e.Bounds.X - delColumnWidth + 1, e.Bounds.Y + 1, e.Bounds.Width + delColumnWidth - 2, e.Bounds.Height - 2)); e.Graphics.DrawString("操作", new Font("宋体", 9f), new SolidBrush(e.Info.Appearance.ForeColor), new Rectangle((e.Bounds.X - delColumnWidth) + (e.Bounds.Width + delColumnWidth) / 2 - 15, e.Bounds.Y + 8, 30, 15)); } } }
3. 效果如下
五. Grid 绘制复选框和全选框
1. 创建 复选框列(check)
2. 添加 GridView 方法 CustomDrawCell，绘制复选框
/// <summary> /// 自定义绘制删除、修改单元格 /// </summary> private void gvDetail_CustomDrawCell(object sender, DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e) { GridView currentView = sender as GridView; if (e.Column == check) { ControlPaint.DrawCheckBox(e.Graphics, new Rectangle(e.Bounds.X + e.Bounds.Width / 2 - 8, e.Bounds.Y + 3, 16, 16), checkBoxState[e.RowHandle]); } }
3. 添加 GridView 方法 CustomDrawColumnHeader，绘制全选框
/// <summary> /// 自定义绘制操作列表头 /// </summary> private void gvDetail_CustomDrawColumnHeader(object sender, DevExpress.XtraGrid.Views.Grid.ColumnHeaderCustomDrawEventArgs e) { if(e.Column != null) { if (e.Column == check) { e.Info.InnerElements.Clear(); e.Painter.DrawObject(e.Info); e.Handled = true; ControlPaint.DrawCheckBox(e.Graphics, new Rectangle(e.Bounds.X + e.Bounds.Width / 2 - 8, e.Bounds.Y + 6, 16, 16), allSelectState); } } }
4. 添加 GridView 方法 Click ，判断全选框是否被点击，若有则重绘所有复选框
/// <summary> /// 判断Grid全选框是否被单击 /// </summary> /// <param name="gridView"></param> /// <param name="name"></param> /// <returns></returns> public bool ClickGridCheckBox(DevExpress.XtraGrid.Views.Grid.GridView gridView, string name) { bool result = false; if (gridView != null) { DevExpress.XtraGrid.Views.Grid.ViewInfo.GridHitInfo info; Point pt = gridView.GridControl.PointToClient(Control.MousePosition); info = gridView.CalcHitInfo(pt); if (info.InColumn && info.Column != null && info.Column.Name == name) { return true; } } return result; } private void gvDetail_Click(object sender, EventArgs e) { if (ClickGridCheckBox(this.gvDetail, "check")) { allSelectState = allSelectState == ButtonState.Checked ? ButtonState.Normal : ButtonState.Checked; selCount = allSelectState == ButtonState.Checked?0:checkBoxState.Count; for (int i = 0; i < checkBoxState.Count; i++) { SetCheckBoxState(i, allSelectState); } } } /// <summary> /// 重新绘制复选框 /// </summary> /// <param name="rowHandle"></param> /// <param name="state"></param> private void SetCheckBoxState(int rowHandle, ButtonState state) { checkBoxState[rowHandle] = state; //获取点击单元格左上角的坐标 GridViewInfo info = gvDetail.GetViewInfo() as GridViewInfo; GridCellInfo cellInfo = info.GetGridCellInfo(rowHandle, check); ControlPaint.DrawCheckBox(gcDetail.CreateGraphics(), new Rectangle(cellInfo.Bounds.X + cellInfo.Bounds.Width / 2 - 8, cellInfo.Bounds.Y + 3, 16, 16), state); }
5. 效果如下
