如何在ASP.NET C＃中的gridview行创建事件中输入控件 [英] How to enter control in gridview row created event in ASP.NET C#

问题描述

hi
我想在gridview中创建一个子标头，第一个标头工作正常。但对于第二个标题，我使用了行创建的事件。但这不能正常工作。任何人都会指导我如何在第二个标题的每一列上输入文本框以获取过滤数据。

提前谢谢

我的代码如下。

{




$ b



GridViewRow HeaderGridRow =新的GridViewRow（0,0，DataControlRowType.Header，Da taControlRowState.Insert）;







TableCell HeaderCell = new TableCell（）;

HeaderCell.Text =过滤记录;

TextBox tb = new TextBox（）;

e.Row.Cells [0] .Add（tb）;

HeaderCell.ColumnSpan = 1;

HeaderGridRow.Cells.Add（HeaderCell）;

GridView1.Controls [0] .Controls.AddAt（ 0，HeaderGridRow）;

//和mor单元类似的方式

推荐答案

您需要检查Header RowType而不是DataRow，以便将代码添加到标头中。您是否尝试过调试代码？

You need to check for Header RowType instead of DataRow so your code will be added to the header. Have you tried debugging your code?

protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
	if(e.Row.RowType == DataControlRowType.Header)
	{
		//your code here for adding the TextBox to the Header

	}
}
