POAdding a CheckChanged event handler to CheckBox inside a dynamically added UserControl
text
Body
copied!<p>I have a UserControl that contains a CheckBox and a TextBox:</p> <pre><code><asp:CheckBox runat="server" ID="chk1" /> <asp:TextBox runat="server" ID="tb1" /> </code></pre> <p>On Page_Load I'm adding several of them dynamically them to a Panel on the page:</p> <pre><code> //loop through the results from DB foreach (Thing t in Things) { //get the user control MyUserControl c1 = (MyUserControl )Page.LoadControl("~/UserControls/MyUserControl.ascx"); //set IDs using public properties c1.ID = "uc" + t.ID; c1.CheckBoxID = "chk" + t.ID; cl.TextBoxID = "tb" + t.ID; //add it to the panel myPanel.Controls.Add(c1); //add the event handler to the checkbox ((CheckBox)myPanel.FindControl(c1.ID).FindControl(c1.CheckBoxID)).CheckedChanged += new EventHandler(CheckBox_CheckedChanged); } </code></pre> <p>I then created the method for the event handler in the same page:</p> <pre><code>protected void CheckBox_CheckedChanged(object sender, EventArgs e) { string test = "breakpoint here"; } </code></pre> <p>When I put a breakpoint inside CheckBox_CheckedChanged it's never hit when the my checkbox gets clicked. </p> <p>When I look at the view source, this is the code that gets generated:</p> <pre><code><input id="ctl00_body_uc1_chk1" type="checkbox" name="ctl00$body$uc1$chk1" checked="checked" /> </code></pre> <p>So, it doesn't seem to be picking up when I add the event handler. It's weird, cause it picks up everything else though.</p> <p>Am I missing something?</p>
