Postback problem with dynamically added ModalPopupExtender

In my task i have to create ModalPopupExtender dynamically, and add an .ascx control to it. This is the code:

Test.aspx page:

<

asp:ScriptManagerProxyrunat="server"ID="proxy"/>

<

asp:UpdatePanelrunat="server"ID="ajaxPanel"RenderMode="Inline"UpdateMode="Conditional"><ContentTemplate><asp:Panelrunat="server"ID="panel"><asp:Buttonrunat="server"ID="btn2"Text="Show Control"OnClick="btn2_Click"/></asp:Panel>

<%

--<asp:Button runat="server" ID="btn1" Text="test1" OnClick="btn1_Click" />--%>

</ContentTemplate></asp:UpdatePanel>

test.ascx control:

<

asp:ScriptManagerProxyrunat="server"ID="proxy"/>

<

asp:UpdatePanelrunat="server"ID="ajaxPanel2"RenderMode="Inline"UpdateMode="Always"><ContentTemplate> <asp:Buttonrunat="server"ID="btnTest2"Text="test2"OnClick="btnTest2_Click"/></ContentTemplate></asp:UpdatePanel><asp:Buttonrunat="server"UseSubmitBehavior="false"ID="btnTest"Text="Close OK"OnClick="btnTest_Click"/><asp:Buttonrunat="server"UseSubmitBehavior="false"ID="btnTestClose"Text="Close"OnClick="btnTest_Click"/>

In aspx page:

protected

overridevoid OnInit(EventArgs e)

{

base.OnInit(e);Control c = LoadControl("~/test.ascx");

c.ID =

"customModalControl";Panel p =newPanel();

p.Width = 300;

p.Height = 200;

p.CssClass =

"modalPopup";

p.ID =

"modalPanel_";_modalPopup =newModalPopupExtender();

_modalPopup.ID =

"modalPopup";

_modalPopup.DropShadow =

true;

_modalPopup.BackgroundCssClass ="modalBackground";

_modalPopup.PopupControlID = p.ID;

_modalPopup.TargetControlID = btn2.ID;

Control c2 = c.FindControl("btnTest");

_modalPopup.OkControlID = c2.ClientID;

c2 = c.FindControl("btnTestClose");

_modalPopup.CancelControlID = c2.ClientID;

p.Controls.Add(c);

panel.Controls.Add(_modalPopup);

panel.Controls.Add(p);

}

protectedvoid btn1_Click(object sender,EventArgs e)

{

}

protectedvoid btn2_Click(object sender,EventArgs e)

{

_modalPopup.Show();

}

onInit event, i create ModalPopupExtender and a panel for ascx control. All works fine, but is one problem, when i click btnTest2 on ModalPopup, rises postback for the page, but ascx control didn't receive btnTest2 _OnClick event. Maybe someone know where is a problem. Thank you.

Try to change change some of your codes to specify asynchronous post back.
<asp:UpdatePanel runat="server" ID="ajaxPanel2" RenderMode="Inline" UpdateMode="Always">
<ContentTemplate>
??????<asp:Button runat="server" ID="btnTest2" Text="test2" OnClick="btnTest2_Click"/>
</ContentTemplate>
<triggers>
????<asp:AsyncPostBackTrigger ControlID="btnTest2" EventName="Click"/>
</triggers>
</asp:UpdatePanel>
Wish this can help you.
