Hello!
I am working on an application that uses grid view with checkboxes. When checkbox value is changed, it calls ValueChanged event with radGridView.EndEdit() and then calls CellValueChanged to read new data.
I want to expand checkboxes functionality with Three State mode however I want user only to be able to switch between normal On and Off states, while the Indeterminate state can only be assigned from the code. I want to make it so user can either go On -> Off, On -> Off or Indeterminate -> Off, and not On -> Indeterminate .
The thing is, I can't find a right event, that should be called when checkbox value is changed and change it, so user cannot reach null state by clicking it. Normally, in Three State mode, when user clicks on checkbox in On state, Indeterminate state is called. I want to switch this state to Off before reading the data.
I hope I've explained my problem clearly enough. Thank you for reading my post :)
