Since I do not know your exact project setup I am not able to reproduce the automatically expanding groups issue. | am attaching a sample project in which the grouping functionality is working fine. Can you please modify it in a way that reproduces this scenario.
As for your second question concerning the UI to be updated. Rebinding is a possible solution but will degrade the performance of RadGridView
. The recommended way to update the UI when a value is being changed in code is to raise the CollectionChanged
event of RadGridView Items collection
. This can be achieved by calling EditItem
methods. Please refer to the Edit an item outside RadGridView
documentation article to check how to properly use them.
I am looking forward to your answer.
