Hi,

Can you please remove the runtimeVersionv2.0 from the dialog handlers, e.g.

<add name="Telerik_Web_UI_DialogHandler_aspx" path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" preCondition="integratedMode" />

If this does not help, open the web.config file and replace Telerik.Web.UI.DialogHandler.aspx with Telerik.Web.UI.DialogHandler.axd
and set the DialogHandlerUrl property to "~/Telerik.Web.UI.DialogHandler.axd"

as suggested in the following article: Web.config registration missing! The Telerik dialogs require a HttpHandler registration in the web.config file.

All the best,
Rumen

Hi Rumen,

i got the issue....
That is not working because of URL rewrite.

I have fixed that by adding foll. code in <rewrite> web.config

<add input="{URL}" pattern="Telerik.Web.UI.DialogHandler.aspx" negate="true" />
<add input="{URL}" pattern="Telerik.Web.UI.WebResource.axd" negate="true" />

full code -

<rewrite>
           <rules>
               <rule name="RewriteASPX">
                   <match url="(.*)" />
                   <conditions logicalGrouping="MatchAll">
                       <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
                       <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
                       <add input="{URL}" pattern="WebResource.axd" negate="true"/>
                       <add input="{URL}" pattern="ScriptResource.axd" negate="true"/>
                       <add input="{URL}" pattern="Telerik.Web.UI.DialogHandler.aspx" negate="true" />
                       <add input="{URL}" pattern="Telerik.Web.UI.WebResource.axd" negate="true" />
                       <add input="{URL}" pattern=".js" negate="true"/>
                   </conditions>
                   <action type="Rewrite" url="memberlogin.aspx?member={R:0}" />
               </rule>
           </rules>
       </rewrite>

   </system.webServer>
