Telerik.Web.UI 2013.2.717.35 & SharePoint 2013 - Causing conflict with wpadder.js to throw type mismatch error

[John]

Note: Sorry wrong SharePoint version in thread title which i can't change! The problem is happening in SharePoint 2010

Hi,

We are currently getting errors when using the latest version of Telerik.Web.UI 2013.2.717.35 in some SharePoint 2010 web parts we develop. The problem seems to be a conflict between the Telerik Javascript files and the SharePoint Javascript file wpadder.js which is triggered once you have added a web part using Telerik to a page and try and click add to add another, the error return is as follows:

SCRIPT5: Type mismatch.
 wpadder.js, line 2 character 13993

This error doesn't happen with the previous version of Telerik.Web.UI 2013.1.417.35 we were using so I assume its to do with some changes that have been added to 2013.2.717.35.

Is there a fix for this problem? Is it a known issue?

Thanks,
JC

Any feedback on the above issue?

Hi JC,

The information you provided in your post is insufficient to reproduce the problem on our test server. Please, explain which RadControls you are using in your web parts and in what SharePoint site and scenario you are adding them. Also it will be of great help, if you can provide we with a simple web part, which I can deploy to our test server and reproduce the issue locally, .

Hi Stanimir,

We've run into the exact same issue. We upgraded to 2013.2.717 and we are getting the same error when trying to add a second web part to the page. I've tried to narrow down which web part is causing the issue, but it is difficult because our web parts are using quite a few Telerik controls. I'll have to create some custom web parts that each only use a single Telerik control so that I can narrow down the search.

I'll come back with more when I narrow down the issue.

I've confirmed that the issue is with the Grid control. I created a simple web part that has nothing except for an empty Grid control and as soon as I try to add a second web part to the page I get the error.

I'm going to open up a support ticket and provide the web part project that I created.

Nic, I'm having the exact same issue. Did you get a resolution from support? If yes, what was the fix? Thanks.

Hi Michael,

The issue with the grid should be fixed in Q3 2013, so I would advise upgrading to the latest release (currently Q3 2013 SP2).

In the meantime you can try adding this JavaScript override after your grid:

Telerik.Web.UI.RadGrid.prototype._fixIndexOfUnderIE8AndLower = function ()
{
 //empty method
}
