this.MasterTableView.Columns.Clear() does not clear the private variable this.viewStateNotManagedCount

[Ole Oscar]

It can be reproduced by creating some columns, then clear and then add less columns that the initial numbers of columns.

Then the control throws an exception in SaveViewState saying the index is out of range.

Hello Ole,

If you are creating the RadGrid dynamically you should use the approach described in the following article. Please give it a try and see how it works for you.
