RadGrid postback issues in SharePoint 2010 Visual WebPart

[JR]

I've run into a number of issues with a RadGrid control (containing a nested grid) which is used in a Visual Web Part for SharePoint 2010.  We are using the 2011.2.712.35 of the ASP.Net AJAX controls.

1) When a user clicks to either add a new grid item, or edit an existing one; the page posts-back and wipes out the left-hand navigation on the page. (see attached image)

2) When editing or inserting items; any button triggering a grid command (performinsert, update, cancel, refresh) does not refresh the grid and the user must browse away from the page and then back again.  It does appear that data is correctly updated or saved; but the form does not close or and the grid does not refresh.  Not sure if this may be related to the first item or not...

The code files are quite long; can they be attached rather than copy / pasted?

3) I also have a RadUploadAsync control in the the EditForm of the grid which does not appear to upload images properly. I'm sure this an RadUploadAsync + SharePoint + web.config issue; so I'd like to get the first two items sorted out first.

Hello,

 Do you use ajax on this page and if so is it configured properly as shown here. All the three issue seem to be related to the same problem that the postback does not happen properly which might be caused by incorrect ajax configuration. I will appreciate if you could also attach the code files for the problematic web part so we can check them on our side.

The link you provided appears to be for SharePoint 2007.  Is the configuation the same for 2010 or does it differ in any way?

Hi,

 The settings are pretty much the same. You can use the attached sample web part as a starting point. It is configured to run and use RadAjaxManager in Sharepoint 2010.

Kind regards,

Still didn't quite solve the problem; but due to time constaints we've had to implement a work around.  We removed the AJAX code and now the upload works properly; but the RadEditor tool still doesn't quite work so we just have a multi-line text box.

I'll do some addtional testing in a few weeks.
