Due to the virtualization mechanism that RadVirtualGrid
currently uses, when you resize the columns, some of the columns may become invisible and other may get visible. That is why the CellValueNeeded
event is triggered to ensure that the proper values will be displayed within the cells. However, I have logged it in our feedback portal
in order to investigate if it is possible to improve the virtualization mechanism in this case.. You can track its progress, subscribe for status changes and add your comments on the following link - feedback item.
I have also updated your Telerik points.
I hope this information helps. If you have any additional questions, please let me know.
