Question

User1052662409 posted

Hi all,

        I just migrate an application from .NetFramwork (2.0+3.5) to 4.0. In that I used ajax. I did thi application with the help of VisualStudio2005. But Now I am using Visual WebDeveloper 2010 Express edition.

So whenever I access the forms where I have used Ajax, It shows a msgbox[ see the screenshot below].

untill I continue it, it'll not run.

How to overcome this.

Thanks.

Gaurav

 In web.config add the following lines

<add assembly="AjaxControlToolkit, Version=3.5.40412.0, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e"/>

Goes between <assemblies></assemblies> tag.

<add tagPrefix="ajaxToolkit" namespace="AjaxControlToolkit" assembly="AjaxControlToolkit, Version=3.5.40412.0, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e"/>                                

Goes between <controls></controls>

Plz verify the Assembly versions may be varry
