推荐答案

你需要在popupextender show之后做绑定gridview ...例如

you need to to do bind gridview after popupextender show...for example

protected void btnEdit_Click(object sender, ImageClickEventArgs e)
{
ImageButton btndetails = sender as ImageButton;
GridViewRow gvrows = (GridViewRow)btndetails.NamingContainer;
this.ModalPopupExtender1.Show();
bind gridview here...
}

使用 ToolkitScriptManager 而不是 ScriptManager 。



它正在工作。我查了一下。

Use ToolkitScriptManager instead of ScriptManager.

It's working.I checked it.
