我想在页面加载时找到标题模板文本框控件

解决方案

试试这个：

  foreach  （GridViewRow gdv  in  GridView1.Rows）{
  if （gdv.RowType == DataControlRowType。标题）
 {
  //  在此处查找控件。 
 TextBox txt =（TextBox）gdv.HeaderRow.FindControl（  txt）; 
} 
}

                           </asp:TemplateField>

I want to find header template textbox control on page load

解决方案

Try this:

foreach(GridViewRow gdv in GridView1.Rows){
     if (gdv.RowType == DataControlRowType.Header)
     {
         //Find the control here.
         TextBox txt = (TextBox)gdv.HeaderRow.FindControl("txt");
     }
}
