    copied!<p>This has got me stumped. I am trying to find a checkbox in a dynamically loaded asp.net Repeater template. The template works fine and the databinding is fine and everything displays fine but I can't find the control! Any ideas?</p> <p>This is the repeater code (I have a similar one for the alternate template with a different style):</p> <pre><code>&lt;%@ Control Language="C#" AutoEventWireup="true" CodeFile="template-tasks- incomplete.ascx.cs" Inherits="controls_template_tasks_incomplete" %&gt; &lt;ItemTemplate&gt; &lt;div class="task"&gt; &lt;div class="date"&gt;&lt;asp:CheckBox ID="chkIsComplete" runat="server" AutoPostBack="True" /&gt;&lt;%# DataBinder.Eval(((RepeaterItem)Container).DataItem, "DateCreated")%&gt;&lt;/div&gt; &lt;div class="description"&gt;&lt;%# DataBinder.Eval(((RepeaterItem)Container).DataItem, "TaskDescription")%&gt;&lt;/div&gt; &lt;/div&gt; &lt;/ItemTemplate&gt; </code></pre> <p>This is how I load the templates (works fine)</p> <pre><code>rptTasks.ItemTemplate = LoadTemplate("~/controls/template-tasks-incomplete.ascx"); rptTasks.AlternatingItemTemplate = LoadTemplate("~/controls/template-tasks-incomplete-alt.ascx"); </code></pre> <p>...and finally this is how I try to find the checkbox (but keeps coming up null)</p> <pre><code>protected void rptTasks_ItemDataBound(object sender, RepeaterItemEventArgs e) { if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item) { CheckBox chkBoxIsComplete = (CheckBox)e.Item.FindControl("chkIsComplete"); if (chkBoxIsComplete != null) { int taskID = (int)DataBinder.Eval(e.Item.DataItem, "TaskID"); } } } </code></pre> <p>I can only think the checkbox is buried deeper in the hierarchy somewhere, but I'm not sure how to access it as I thought FindControl would do it.</p> <p>This is the HTML that's generated:</p> <pre><code>&lt;ItemTemplate&gt; &lt;div class="task"&gt; &lt;div class="date"&gt;&lt;input id="ctl00_ContentPlaceHolder1_rptTasks_ctl00_ctl00_chkIsComplete" type="checkbox" name="ctl00$ContentPlaceHolder1$rptTasks$ctl00$ctl00$chkIsComplete" onclick="javascript:setTimeout('__doPostBack(\'ctl00$ContentPlaceHolder1$rptTasks$ctl00$ctl00$chkIsComplete\',\'\')', 0)" /&gt;23/08/2010 11:53:00 PM&lt;/div&gt; &lt;div class="description"&gt;test task&lt;/div&gt; &lt;/div&gt; </code></pre> <p></p>
