ModalPopupExtender

[Peter]

I am trying to use ASP.NET Ajax Control Toolkit ModalPopupExtender which
works fine, but what I am trying to do is:

1) User Clicks on the button:
2) Function on the server will check for a status
3) Only display ModalPopupExtender if the status is True.

How do I do that, how do I display ModalPopupExtender only after postback?
Is that possible?
Thank You
Peter

Hi Peter,
Is it what you need?

Aspx.cs:
protected void Page_Load(object sender, EventArgs e)
{
this.ModalPopupExtender1.Enabled = false;
}

protected void Button1_Click(object sender, EventArgs e)
{
if (true)//condition here
{
this.ModalPopupExtender1.Enabled = true;
}
}

Aspx:
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>

<asp:Label ID="Label1" runat="server" Text="Click Me After
ModalPopupExtender is Enabled" BackColor="Yellow"></asp:Label>
<asp:Button ID="Button1" runat="server" Text="Enable
ModalPopupExtender" onclick="Button1_Click" />
<asp:Panel ID="Panel1" runat="server" style="display:none" >
Hello</asp:Panel>
<cc1:ModalPopupExtender ID="ModalPopupExtender1"
runat="server" PopupControlID="Panel1" TargetControlID="Label1" >
</cc1:ModalPopupExtender>
</ContentTemplate>
</asp:UpdatePanel>

Please have a try and let me know if it works. If it's not what you need
please clarify your requirement.
