[Solved] telerik.grid.js error

[Charley]

I am getting this terrible error.  I am not certain why.  I am including the error and line of js telerik js file as well.

error information.
Error: this.dataSource is undefined
Source File: telerik.grid.js
Line: 1498

this is in the layout page

@(
       Html.Telerik().ScriptRegistrar()
           .DefaultGroup(group => group
               .Add("telerik.grid.editing.js")
               .Compress(true)
           )

   )

Here is the razor page.  This code worked before and mysteriously stopped working.  I obviously made some sort of innocuous change that broke something. This is only part of the razor code.  Thanks for the reply.

Found the problem.  I was a victim of updated JavaScript files from colleague.  Thanks for looking any ways.  Regards

We were using the version of Telerik controls before q2 2011.  We are have updates.  What is the difference between the calls to fill the grid in the new version. 


Thanks for the reply.

I'm getting a similar error and can't figure it out for the life of me.

We also were using an older version and the dataBind method is throwing that same error after the Telerik controls update.

What exactly was your problem?

Any help in diagnosing my problem would be great. :-)

What I ended up doing is using the IE9 DOM inspector and its javascript profiler.  I found a problem with a call timing issue or something to that sort.  It was rather silly actually.  It might have even been something being called incorrectly to the new API but it was surely something silly once looked at in the profiler.  I find it useful to put try catche blocks on my javascript in third party api's.  It is very easy for the api to handle all the errors for even the ones they have problems with.  The try catch will allow you to catch things not ordinarily available to you.  Hope this helps.
