HtmlEditorExtender does not show Icons - ajaxcontroltoolkit

Question

As the subject says.
I've bound an HtmlEditorExtender to a textbox but it doesn't show the icons in the toolbar, just grey buttons.

Answer 1

The code should look something like:
<asp:TextBox ID="ContentMail" runat="server" AutoFocus="true" Width="60em" Height="40em" TextMode="MultiLine"/>
<asp:HtmlEditorExtender ID="HtmlEditorExtender1" runat="server" TargetControlID="ContentMail" DisplaySourceTab="True">
</asp:HtmlEditorExtender>
And if you are setting it in a TemplateField just add an invisible div with a textbox linked with a HtmlEditorExtender

Answer 2

I've experienced the same with AjaxControltoolkit 15.1, when I applied Ajax Control Toolkit Static Resources. I had to detach ACTStaticRecourses in order to get my icons back in the toolbar.
Hope this helps to some :)

hey guys(girls) if you using update panel in asp.net or asp:HtmlEditorExtender using in gridview and don't show icons. You needed add hide asp.panel when contain asp:HtmlEditorExtender and textbox. Example.
<asp:Panel runat="server" Visible="False">
<asp:TextBox ID="TextBox22" runat="server" AutoFocus="true" BackColor="White" Height="15em" TextMode="MultiLine" Width="99%"></asp:TextBox>
<ajaxToolkit:HtmlEditorExtender ID="TextBox12_HtmlEditorExtender" runat="server" TargetControlID="TextBox22">
</ajaxToolkit:HtmlEditorExtender></asp:Panel>
