        }
        return _Items.Substring(0, _Items.Length - 1);

        CheckOmaniData();
    }

推荐答案

您可以使用rowcommand代替当前的编码.

将CommandName赋予gridview中的Chechbox.说"Check1"

您必须在gridview的RowCommand事件上执行代码.检查以下示例

Hi,

You can use rowcommand instead of current coding.

Give CommandName to Chechbox in gridview. say "Check1"

You have to do the code on RowCommand event of gridview. check following example

void ProductsGridView_RowCommand(Object sender, GridViewCommandEventArgs e)
 {
   // CommandName property to determine which button was clicked.
   if(e.CommandName=="check1")
   {
     // code on checkbox select
   }
}
