  1. POUpdatePanels in a UserControl Loaded through LoadControl() don't work?
    text
    copied!<p>I hope you can help as i've been banging my head against the wall for a while. Long story short, I want to dynamically load UserControls with LoadControl which contain their own updatepanels, and when they're on the page, be able to trigger their updates individually via their children.</p> <p>To explain better, see my extremely simplified example of my issue:</p> <p><strong>Default.aspx</strong></p> <pre><code>&lt;form id="form1" runat="server"&gt; &lt;asp:ScriptManager ID="ScriptManager1" runat="server"&gt; &lt;/asp:ScriptManager&gt; &lt;div&gt; &lt;asp:PlaceHolder ID="PlaceHolder1" runat="server"&gt;&lt;/asp:PlaceHolder&gt; &lt;/div&gt; &lt;/form&gt; </code></pre> <p><strong>Default.aspx.vb</strong></p> <pre><code> IF Me.IsPostBack = False Dim control As Control = LoadControl("WebUserControl.ascx") PlaceHolder1.Controls.Add(control) Dim control2 As Control = LoadControl("WebUserControl.ascx") PlaceHolder1.Controls.Add(control2) Dim control3 As Control = LoadControl("WebUserControl.ascx") PlaceHolder1.Controls.Add(control3) End If </code></pre> <p><strong>WebUserControl.ascx</strong></p> <pre><code>&lt;asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="true"&gt; &lt;ContentTemplate&gt; &lt;%= Now.ToLongTimeString%&gt; &lt;asp:Button ID="Button1" runat="server" Text="Button" /&gt; &lt;/ContentTemplate&gt; </code></pre> <p></p> <p>If you ran this, i would like each control to be loaded, added to the placeholder, and then when you click the button in that control, only that control trigger an update.</p> <p>Instead it doesn't seem to work.</p> <p>If i add the controls to the page by using the usual tags, they work fine, so the issue is somewhere in the loadControl/placeholder issue.</p> <p><strong>PLEASE HELP!</strong></p>

An individual column

Larger individual text columns get their own page to allow for proper reading.
