Filtering master-detail data grids using select and deselect events

Hello,


I'm facing an issue with my master-detail data grids, and I'm not sure how to resolve it. I have implemented select and deselect events on the master grid. When a row is selected in the master grid, I filter the detail grid. Similarly, when a row is deselected, I filter the detail grid so that it doesn't return anything.


The filtering works well, but I'm encountering a problem when I select another row while one is already selected. In this case, the deselect event is triggered first, which filters the detail grid, and then the select event is triggered, which again filters the detail grid. Is there a way to determine if another row is going to be selected, so that I can skip the deselect event and only call the select event? This would ensure that the filtering happens only once.


I would appreciate any help or suggestions you might have regarding this issue. Thank you!
