Asp:

I have set a modalpopup extender to display the item of a dropdowmlist in it.but upon clicking the button nothing is poping up..need help..

        <ContentTemplate>
        <asp:Button ID="Button1" runat="server" Style="display:none" />
        <asp:ModalPopupExtender ID="ModalPopupExtender1" runat="server"

           TargetControlID="Button1" PopupControlID="Panel1" CancelControlID="CancelButton">

5.在下一页的下一页，放置一个Button和一个TextBox，如下所示:

5.Next the next page, placed a Button and a TextBox like this:

<asp:TextBox ID="MyTextBox" runat="server" />
<asp:Button ID="MyButton" runat="server" Text="Popup" OnClick="MyButton_OnClick" />

6，在页面后面的代码中，我放置了MyButton的处理程序:

6.and in the code behind for the page, i placed the handler for MyButton:

protected void MyButton_OnClick(object sender, EventArgs e)
{
     Label1.Text = MyTextBox.Text;
     UpdatePanel1.Update();
     ModalPopupExtender1.Show();
}
