ASP.NET Ajax framework failed to load client side framework
I face below errors at a same time.
ASP.Net Ajax framework failed to load client side framework
Microsoft JScript runtime error: 'Sys' is undefined
Microsoft JScript runtime error: 'Sys' is undefined
and Telerik is undefined.
If somebody else also got this error, below is what i did to resolve this error.
I had below in my web.config
<add name="Telerik_Web_UI_WebResource_axd" path="Telerik.Web.UI.WebResource.axd"
type="Telerik.Web.UI.WebResource" verb="*"
preCondition="integratedMode,runtimeVersionv2.0"/>
type="Telerik.Web.UI.WebResource" verb="*"
preCondition="integratedMode,runtimeVersionv2.0"/>
I removed runtimeversion2.0 and it worked well.
Just to update you that it was working well in IIS6.0 but error occured when i deploy it on IIS7.0
So the above entry was in <system.webServer> tag, which is basically for iis7 specific.
It took my lot of time to resolve this issue.
