ASP.NET VS2008 Ajax Problem

Question

Hi Guys,

I am using VS2008 Pro and the problem is the following.

I need to add eg.

<asp:ScriptManager ID="ScriptManager1" runat="server"/>

<ajaxToolkit:FilteredTextBoxExtender ID="Filter1" runat="server" ValidChars="AEIOU" TargetControlID="TextBox1"></ajaxToolkit:FilteredTextBoxExtender>

This problem is that <ajaxToolkit........ are not being detected by intellisense. I added the reference AjaxControlToolkit.dll but I still can't use them

Thanks

I believe the problem is you haven't registered the tagPrefix.

Try adding the following line to your web.config.

<pages>
  <controls>
    <add tagPrefix="ajaxToolkit" namespace="AjaxControlToolkit" assembly="AjaxControlToolkit"/>
  </controls>
</pages>

This should go in the system.web section. You may already have a pages/controls section defined, in which case, just add the "add" element to the control section.
