[Solved] How to validate duplicate items in a batch editing grid.

[Oscar]

Hello Telerik:
Do you have any sample where the new rows inserted by the user have a 'exists' rule validation to prevent duplicate items in a batch editing grid?
Thank you.
Oscar.

Hi Oscar,

 We don't have such example, but this is a general case, that is not directly related to the Grid component and should be handled by custom user code. Basically, what you need to do is to implement a custom check in the save action (_SaveBatchEditing in the demo) and in case of a problem like a duplicate item, to raise  ModelState error. The function hooked to the Grid's OnError event will display that error to the user.

All the best,
