- Create a new project containing RadGridView
- Build hierarchy with large text data in cells
- Set the AutoSizeRows property to true and AutoSizeColumnMode to Fill
- Run the project, scroll down and try to click on a cell

Save\Load functionality of the control should work with ColumnGroupsViewDefinition.

Currently it is not possible to change the table header row height when using column groups view definition.

Currently when RadGridView contains multiple header rows and its layout is being saved, after loading it the grid shows "No data to display" although it is binded to a data source. 

Add a functionality to support saving the layout when RadGridView contains multiple header rows

We should consider the Display attribute when using business objects as data source in RadGridView.

We have a RadGridView, which uses a custom object for data source and that object override Equals method from INotifyPropertyChanged interface. If Equals return true for records that actually aren't equal, than the RadGridView takes(displays) them as equal (with one and the same values), despite the fact that in underling data source they are still different.
