Hi ,
I have a GridView with the following kind of columns :
GridViewComboBoxColumn
GridViewDataColumn ( ReadOnly)
GridViewDataColumn ( Editable)
When I navigate away from a GridViewComboBoxColumn in edit mode to any other Editable column(in a different row) which is not of type GridViewComboBoxColumn, I get the following error
Unhandled Error in silverlight Application
Code :4004
Category:ManagedRuntimeError
Message:system.NullReferenceException
at
Telerik.Windows.Controls.GridView.GridViewCell.ResumeCurrentState()
Telerik.Windows.Controls.GridView.GridViewCell.OnCellLoaded
Telerik.Windows.Controls.GridView.GridViewCellBase.GridViewCellBase_Loaded
Any help in this regard is appreciated.
Best

Hi Pavel ,
I could not reproduce the problem in your example. I am populating the grid with dynamically generated objects ( all the properties are of of type System.RunTime type). The problem that I have described is specific to the case of dynamically generated objects .
Are you aware of any issues related to the above scenario?

Hello Lakshmi,
I am now aware of issues with the ComboBox column and System.RunTime type.
However I do not exclude the possibility for a bug present in the ComboBoxColumn logic for member access.
It would be very helpful if you could provide some code illustrating how you create and bind your business objects to the grid and to the cobmbobox column .
In case we find any bug in the RadGridView a fix will be provided for the very next internal build.
Sincerely yours,
