ModalPopupExtender

[GaryDean]

After watching the video on the ModalPopupExtender from MSDN I designed a
panel with some controls on it: A dropdown box, an ok button, a cancel
button. Unfortunitely, the video only shows how to trigger client side
javascript and not server side events(Grrrrrr). I supposed that I simply
have to handle events from the controls on the panel.

Well, when I change values in the dropdown, or push the buttons on the
panel, the server side events do indeed trigger but the modal box goes
away!! how can I keep it displayed until it is dismissed by, say, a button
identified by the ModalPopupExtender OkControlId entry.

The general idea here is that I want to have somewhat of a complex form on
this panel with all sorts of controls. is this possible?
Thanks,
Gary

the ModalPopupExtender is only a javascript visual effect (unhides a div). if
you do a postback in it it postbacks. you make serverside call with the
client ajax library. if you can not code javascript, you can also put an
update panel inside the popup panel, and do an async postback.

Hi Gary,

What Bruce said is reasonable. Here's the code that demonstrates how to do
this:

aspx:

<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:Label ID="Label2" runat="server" Text="Click Me to Show Popup
Window!" BackColor="Yellow"></asp:Label>
<cc1:ModalPopupExtender ID="Label2_ModalPopupExtender"
runat="server"
TargetControlID="Label2"
OkControlID="Button3" DropShadow="true"
PopupControlID="Panel1">
</cc1:ModalPopupExtender>
<aspanel ID="Panel1" BackColor="Pink" runat="server"
style="display:none;">
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Button ID="Button2" runat="server" Text="Click Me"
onclick="Button2_Click" />
<asp:Label ID="Label1" runat="server"></asp:Label>
<br />

</ContentTemplate>
</asp:UpdatePanel>
<asp:Button ID="Button3" runat="server" Text="OK" />

</aspanel>

aspx.cs:

protected void Button2_Click(object sender, EventArgs e)
{
this.Label1.Text = DateTime.Now.ToString();
}

The basic idea is to use UpdatePanel to do async postback.
