I'm using Nuget latest AjaxControlToolkit ver.16.1.2 and my HTMLEditorExtender is giving this problem when I tried to upload any photo.
The textbox and the HTMLEditorExtender is located inside a repeater in which to be generated multiple controls when a button of the page is clicked and a number specified. Example when user provide 5 and click the button, 5 of the HTMLEditor will be generated.
Below are the errors and also the source. Anybody know how to solve this? Thanks
<asp:TextBox ID="tbxQuestion" runat="server" CssClass="textbox" TextMode="MultiLine" Height="400px" Width="90%" />
<ajaxToolkit:HtmlEditorExtender ID="tbxQuestion_HtmlEditorExtender" runat="server" TargetControlID="tbxQuestion" Enabled="true"
OnImageUploadComplete="tbxDummy_HtmlEditorExtender_ImageUploadComplete" DisplaySourceTab="true" EnableSanitization="false">
