在gridview的末尾插入复选框列 [英] Insert checkbox column at the end of gridview

问题描述

我的GridView包含以编程方式添加的20列(DataTable，DataColumn，DataRow和DataSet).现在，我需要插入一个复选框列作为最后一列(21 ^st 列).我应该如何添加它?

My GridView contains 20 columns which are added programmatically (DataTable, DataColumn, DataRow and DataSet). Now I need to insert a checkbox column as the last column (21^st column). How should I add it?

我尝试在.aspx文件中使用普通的模板字段(从设计"选项卡)添加，但在第一列中添加了一个复选框，在最后一列中添加了不.

I tried adding with the usual Template Field (from design tab) in .aspx file but that adds a checkbox as the first column and not as the last one.

推荐答案

如果要使用 DataTable 绑定 GridView ，请在设置之前执行此操作GridView DataSource .

If you are binding your GridView using a DataTable, do this before you set the GridView DataSource.

dataTable.Columns.Add("Select", Type.GetType("System.Boolean"));

DemoGrid.DataSource = dataTable;
DemoGrid.DataBind();

foreach (GridViewRow row in DemoGrid.Rows)
{
    //check box is the first control on the last cell.
    CheckBox check = row.Cells[row.Cells.Count - 1].Controls[0] as CheckBox;
    check.Enabled = true;
}

在不相关的旁注中，请注意，您的 asp:GridView 实际上是自动生成的.

On an unrelated side note, please note that your asp:GridView is in fact AutoGenerated.
