Hello,
I have 3 columns in my grid and need data validations in the first column.
I'm currently trying to achieve this through IDataErrorInfo.
I'm trying to trigger validation for all cells in the column when any one of the cells is updated or any row is added/deleted.
So far i could not see any generic method to make this work.
From this https://www.telerik.com/forums/trigger-grid-view-validation there is no way to do this?
Any help is appreciated.

Hi Raghavendar,
IDataErrorInfo is a good way to go. Please find attached a modification of our ValidationIDataErrorInfo SDK sample. I added two buttons to it - first one adds new football club with stadium capacity < 50000 and its row is immediately validated (actually model is validated). Second button updates the capacity of the Liverpool club and it's row is re-validated too.
Do you need to validate rows in which no change has happened ? If yes, could you please elaborate a bit more on the exact requirements ?
