DataGridView绑定

今早又一杰作，虽然不完美，但还凑合用，不作过多注释，给初学者动脑筋的机会，学会看懂别人的代码和思路，特别像我这些土代码，更可以磨练你的耐心 -_-#

1 Grid 实体类

  1 public class GridEntity

2 Grid操作类

public class GridBind
    {
        public GridBind() 
        {
            
        }

        /**//// <summary>
        /// 给DataGridView添加列
        /// </summary>
        /// <param name="eDataGridView"></param>
        /// <param name="eList"></param>
        public static void AddColumn(DataGridView eDataGridView, List<GridEntity> eList)
        {
            foreach (GridEntity mGridEntity in eList) 
            {
                eDataGridView.Columns.Add(getColumn(mGridEntity));
            }
        }

        /**//// <summary>
        /// 取得要添加的列
        /// </summary>
        /// <param name="eGridEntity"></param>
        /// <returns></returns>
        private static DataGridViewColumn getColumn(GridEntity eGridEntity)
        {
            switch (eGridEntity.ColumnType) 
            {
                case "Bool":
                    DataGridViewColumn mColBool = new DataGridViewCheckBoxColumn();
                    mColBool.Name = eGridEntity.DataPropertyName;
                    mColBool.DataPropertyName = eGridEntity.DataPropertyName;
                    mColBool.HeaderText = eGridEntity.HeaderText;
                    mColBool.Width = eGridEntity.Width;
                    mColBool.Frozen = eGridEntity.IsFrozen;
                    return mColBool;
                default:
                    DataGridViewColumn mColTextBox = new DataGridViewTextBoxColumn();
                    mColTextBox.Name = eGridEntity.DataPropertyName;
                    mColTextBox.DataPropertyName = eGridEntity.DataPropertyName;
                    mColTextBox.HeaderText = eGridEntity.HeaderText;
                    mColTextBox.Width = eGridEntity.Width;
                    mColTextBox.Frozen = eGridEntity.IsFrozen;
                    return mColTextBox;
                   
            }
        }
    }

3 调用方法

/**//// <summary>
        /// 绑定列表
        /// </summary>
        /// <param name="eDataGridView">DataGridView名</param>
        /// <param name="eGridName">在Sys_GridList数据表中对应的列表名</param>
        protected void BaseBindGrid(DataGridView eDataGridView, string eGridName)
        {
            eDataGridView.Columns.Clear();
            DAL.BaseForm.DALGrid mDALGrid = new DY.DyErp.DAL.BaseForm.DALGrid();
            List<Common.GridEntity> mGridEntityList = new List<DY.Common.GridEntity>();
            foreach (DataRow mDataRow in mDALGrid.getColumnList(eGridName).Rows)
            {
                Common.GridEntity mGridEntity = new DY.Common.GridEntity();
                mGridEntity.GridName = mDataRow["GridName"].ToString();
                mGridEntity.DataPropertyName = mDataRow["DataPropertyName"].ToString();
                mGridEntity.HeaderText = mDataRow["HeaderText"].ToString();
                mGridEntity.Width = Convert.ToInt32(mDataRow["Width"]);
                mGridEntity.ColumnType = mDataRow["ColumnType"].ToString();
                mGridEntity.IsFrozen = Convert.ToBoolean(mDataRow["IsFrozen"]);
                mGridEntity.SortNo = Convert.ToInt32(mDataRow["SortNo"]);
                mGridEntityList.Add(mGridEntity);
            }
            DY.Common.GridBind.AddColumn(eDataGridView, mGridEntityList);
        }
