  1. POProblem with ScriptManager when trying to email rendered contents of ASP.NET page
    text
    copied!<p>I recently added a Telerik control to an ascx that is included in an aspx page. This page has a "Send email" button, which when clicked will email the user the rendered output of the page. The Telerik control I added requires a ScriptManager, so I added that to the ascx. However, now the email button won't work. I get the following error:</p> <p>The control with ID 'myIdHere' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.</p> <p>I know the script manager exists because the page works fine when I go that url, it is only failing when it tries to email the rendered output.</p> <p>Here's a code snippet, any ideas as to whether there is a problem with scriptmanager when doing this sort of thing?</p> <pre><code>Page EmailPage = new EmailBasePage(); System.Web.UI.HtmlControls.HtmlForm EmailForm = new System.Web.UI.HtmlControls.HtmlForm(); EmailPage.Controls.Add(EmailForm); EmailForm.Controls.Add(contentTable); //this is the container with all the controls I want to email StringBuilder SB = new StringBuilder(); StringWriter html = new StringWriter(SB); HtmlTextWriter mhtmlWriter = new HtmlTextWriter(html); EmailPage.DesignerInitialize(); EmailPage.RenderControl(mhtmlWriter); mhtmlWriter.Close(); </code></pre> <p><strong>Update</strong> The control "myIdHere" referenced in the error message is the Telerik RadComboBox control that requires a ScriptManager. It is a child control of the contentTable control that is added to EmailForm. The control hierarchy is like this:</p> <pre><code>contentTable |__UserControl1 |__ScriptManager1 |__UserControl2 |__Control "myIdHere", a Telerik RadComboBox requiring a ScriptManager </code></pre>
