Hi Telerik,
A customer of ours is having this issue with the grid. When the grid first displays all is well. When they scroll down and then scroll back up to the top, the text in one of the columns changes to different values. Unfortunately it is something that we have been unable to replicate in house.
Reviewing our xaml, we note that the GridViewDataColumn columns that are teh problematic are ones where we have a custom CellTemplate defined.
Researching your forum I came across this link: http://www.telerik.com/forums/difference-between-cellstyle-template-and-celltemplate
I have now reworked the xaml to use CellStyle instead of CellTemplate.
In house everything works as is and I am hopeful to supply this change to our customer to have them try it.
In trying to understand if this will help and if so why I used JustDecompile on the Telerik.Windows.Control.GridView.dll and note that in Telerik.Windows.Control.GridView.DataCellsPresenter.SyncProperties() method there is a NotifyPropertyChanged call for CellStyle only. there is no call for CellTemplate.
Should Telerik also have a NotifyPropertyChanged call to CellTemplate in this SyncProperties() method and until it is added should we use CellStyle in our Xaml to assure everything stays synced when Row Virtualization is used?
