The group panel for drag and drop grouping at the top of the grid contains nested tables.  See sample markup below.  Those tables contain empty TH elements which are not displayed (display=none), but still generate errors by our WAI accessibility checker tool.  Is there a property I can set that will set the text for those TH elements?  I've set the 3 offending TH elements in bold below.

 

Thanks,

 

Ray

Hello,

To prevent the errors you received you can try setting the Caption property of the Grid MasterTableView as shown in the respective accessibility demo:
http://demos.telerik.com/aspnet-ajax/grid/examples/accessibility-and-internationalization/accessibility-compliance/defaultcs.aspx

This value will be also used for populating the empty <th> element. Give it a try and let me know in case you still encounter any problems.
