i have a GridGroupingControl and want do disable clicking in the next line when i get an error while line change.

For example:

I want to add a new record with 3 Fields at the top of the grid.
After changing the line or press enter want to check if one these fields is emty. If one field is empty the i want that the user becomes a message like "Error saving Data, because one field is empty".

At this point i want the stay in the current ("Add new line") line at the top (don´t change the line!) that the user has the posibility to add some data to the empty field and try to save the line ones more.

I see a validate value event, that has the behavior i wish to have but i only able to say "only allow numeric". Theres no possibility for me to add an own validation with "checkEmptyFields()" or something like this!

I spend a lot of time find a solution, but i found nothing.

I would be very thankfull, when you can give me urgent help.

best regards,

Take a look at the "DataSourceControlRowAdding" event. There is a handled and a canceled property. Set canceled to true and the line stays in edit mode.
