在DevExpress中GridControl与GridView有什么区别？

dev GridControl实现拖拽

动态生成Grid表格

hjpm中涉及到的事件

DevExpress控件使用

事件

GirdControl只是一个容器控件,必须要求GridView视图作为它的子控件，也就是说GirdControl里面必有至少有一个GridView，GridControl可以包含多个视图，可以实现视图的切换

GridView常见的一些属性设置

gridView1_CustomDrawCell与gridView1_RowCellStyle都可以且用法一样。但是CustomDrawCell更稳定

private void gridView1_CustomDrawCell(object sender, RowCellStyleEventArgs e)
        {
            DevExpress.XtraGrid.Views.Grid.GridView view = sender as DevExpress.XtraGrid.Views.Grid.GridView;
            //列名=a，值=1的标记为绿色
            if (e.CellValue.ToString() == "1" && e.Column.FieldName.ToString().Equals("a"))
            {
                e.Appearance.BackColor = Color.FromArgb(128, 255, 128);
                e.Column.DisplayFormat.FormatString = "yyyy-MM-dd HH:mm:ss";
               
            }
        }

View Code

DataTable dt = ((DataView)gridView1.DataSource).ToTable();

DataRow dtContractRow = this.grdContract.GetFocusedDataRow();

GridColumn c = new GridColumn();
                c.Name = "code";
                c.Caption = "code";
                c.FieldName = "code";
                //c.OptionsColumn.AllowSize = true;
                //c.OptionsColumn.ReadOnly = true;
                //c.OptionsColumn.AllowEdit = false;
                //c.OptionsColumn.AllowMove = false;
                //c.OptionsColumn.AllowSort = DevExpress.Utils.DefaultBoolean.False;
                //c.OptionsColumn.AllowGroup = DevExpress.Utils.DefaultBoolean.False;
                //c.OptionsFilter.AllowFilter = false;
                //c.OptionsFilter.AllowAutoFilter = false;
                //c.Visible = true;
                gv.Columns.Add(c);

View Code

//设置列内容完全显示所需的最佳列宽
gridColumn1.BestFit();

//自动调整所有列的宽度
this.gridView1.BestFitColumns();

DevExpress GridControl使用整理

for (int i = 0; i < gridView1.RowCount; i++)
  {
     if (string.IsNullOrEmpty(gridView1.GetRowCellValue(i, "FieldName") as string))
      {
         gridView1.FocusedRowHandle = i;
         var col = gridView1.Columns.Where(c => c.FieldName == "FieldName").FirstOrDefault();
         gridView1.SetColumnError(col, "该字段不能为空,请重新填写!");
      }
  }

View Code

分组

表头换行

滚动分页

设置字体颜色

空值校验 ValidateRow

拖动

合并表头

格子变色

事件

mainView_CellValueChanged

mainView_CustomColumnDisplayText

mainView_CustomDrawCell

gridcontrol中有5种view 型式

普通的是gridview

cardview

BandedView

Advanced BandedView

LayoutView

如何隐藏 GridControl 的 GroupPanel 表头

设置 Run Design->OptionsView->ShowGroupPanel 设置为：false

Devexpress:在GridControl中使用RepositoryItemGridLookUpEdit 进行级联选择

使用PopupContainerEdit和PopupContainer

 private void SetView()
        {
            GridView gridView = (GridView)this.DefaultView;
            if (gridView != null)
            {
                gridView.StartSorting += new EventHandler(gridView_StartSorting);
                gridView.TopRowChanged += new EventHandler(gridView_TopRowChanged);
                gridView.RowCountChanged += new EventHandler(gridView_RowCountChanged);


                isViewSetted = true;
            }
        }
