Hello, I was actually able to solve my own problem by taking off the RadAjaxPanel and instead adding the RadAjaxManager to Handle both RadGrids. AjaxControlID = RadGridUser and the updated Controls= RadGridUser, RadGridWorkArea, RelatedComboBoxesToolTip
and then create another AjaxControlID = RadGridWorkArea with updated controls = RadGridWorkArea, RelatedComboBoxesToolTip but whenever I go to click Add new record the batchManagerExtentions.js breaks and the _handleToolTipShow: function(sender, args) line and it says it's unable to get property className of undefined or null reference. It is saying that the currentTarget of currentTarget.className.indexOf(REQUIRED_CELL_CLASS) is undefined. I'm really not sure what control it is looking for here and since I'm not to familiar with exactly how this .js file is working I'm having trouble narrowing down a solution. This is one additional question....would there be anyway to disable the Add new record Save changes and Cancel changes buttons until a user in the RadGridUser is clicked? Thanks again for any support.
