C# DevExpress GridControl下动态创建列的方法

这里是把在表格中创建控件的方法封装成一个类，然后在创建列的时候实例化“创建控件”的方法

1.在列中使用一些按钮

表格创建中控件

2.创建添加DataTable数据源

 1  //添加表
 2         private void CreateData()
 3         {
 4             //新建一个dt对象
 5             DataTable dt = new DataTable();
 6             dt.Columns.Add("retrieve", Type.GetType("System.String"));//检索
 7             dt.Columns.Add("coding", Type.GetType("System.String"));//编码
 8             dt.Columns.Add("name", Type.GetType("System.String"));//名称
 9             dt.Columns.Add("quantity", Type.GetType("System.Double"));//数量
10             dt.Columns.Add("id", Type.GetType("System.String"));//数量
11             CreateList();//创建列
12             this.gridData.DataSource = dt;
13         }

3.创建列

13             this.gridView1.Columns.Add(retrieve);

26             name.Width = 120;
27             name.VisibleIndex = 32;
28             name.OptionsColumn.AllowEdit = false;
29             name.ColumnEdit = tableControl.memoEdit;

38             #endregion
