  1. POASP.NET: Custom Control Reloads Whole Page
    text
    copied!<p>I'm working on a ASP.NET site with C# code. Now the trouble starts when I create a custom control programmatically. The control displays in a panel, but when I click one of the buttons of the control it does nothing. If I click them twice, the user control disappears. Using the debugger, I found that it's doing a postback, which is strange because I tried using buttons and setting the <code>usesubmitbehavior</code> to <code>false</code>; it's still sending postbacks.</p> <p>Here is where the control is inserted on the <code>default.aspx</code> file</p> <pre><code>&lt;asp:UpdatePanel runat="server" ID="contentHolderUpdatePanel" UpdateMode="Conditional"&gt; &lt;ContentTemplate&gt; &lt;asp:Panel runat="server" ID="contentPanel"&gt; &lt;/asp:Panel&gt; &lt;/ContentTemplate&gt; &lt;/asp:UpdatePanel&gt; </code></pre> <p>Here is the ASPX from <code>ListadoAuditoria</code> of the control. </p> <pre><code>&lt;asp:UpdatePanel runat="server" ID="auditorTableUpdatePanel" UpdateMode="Conditional"&gt; &lt;ContentTemplate&gt; &lt;asp:Table runat="server" ID="auditorTable" BorderWidth="0" Width="100%"&gt; &lt;asp:TableHeaderRow HorizontalAlign="Center"&gt; &lt;asp:TableHeaderCell&gt;Button &lt;/asp:TableHeaderCell&gt; &lt;/asp:TableHeaderRow&gt; &lt;/asp:Table&gt; &lt;/ContentTemplate&gt; &lt;/asp:UpdatePanel&gt; &lt;asp:UpdatePanel runat="server" ID="formHolderUpdatePanel" UpdateMode="Conditional"&gt; &lt;ContentTemplate&gt; &lt;asp:Label runat="server" ID="testLabel" Text="bbbbbbbbbbbbb" &gt;&lt;/asp:Label&gt; &lt;/ContentTemplate&gt; &lt;/asp:UpdatePanel&gt; </code></pre> <p>The method that the button invokes should change the text of the label <code>testLabel</code> from "bbbbbbbbbbbbb" to "aaaaaaaaaaa". Obviously I'm doing an <code>auditorTableUpdatePanel.Update()</code> after I modify the text.</p> <p>The control CS</p> <pre><code> protected void Page_Load(object sender, EventArgs e) { loadAudits(); } public void loadAudits() { for(int i=0;i&lt;10;++i) { TableRow row = new TableRow(); TableCell cell1 = new TableCell(); ImageButton deleteButton = new ImageButton(); deleteButton.ImageUrl = "~/image.gif"; deleteButton.Click += generateNewPart; deleteButton.EnableViewState = true; deleteButton.ID = i.ToString(); cell1.Controls.Add(deleteButton); row.Cells.Add(cell1); auditorTable.Rows.Add(row); } } public void generateNewPart(object sender, EventArgs e) { tumadre.Text = "aaaaaaaaaaaa"; formHolderUpdatePanel.Update(); } </code></pre> <p>And here is the code when I generate the control and insert it into the panel:</p> <pre><code>Panel panel = (Panel)Page.FindControl("contentPanel"); UpdatePanel updatePanel = (UpdatePanel)Page.FindControl("contentHolderUpdatePanel"); ListadoAuditorias listadoAuditorias = (ListadoAuditorias)LoadControl("~/CargaDeAuditoria/ListadoAuditorias.ascx"); panel.Controls.Add(listadoAuditorias); updatePanel.Update(); </code></pre> <p>I looked over the Internet and didn't found anything.</p>
