Hello, ­­­­­

I am just checking about the progress of this issue. Let me know If you need my further assistance on this  matter?

Thank you for using Infragistics Components.

Hello ,

As far as I understand from your request you want to obligate the customer to enter value for a cell from particular columns (which already exists in  UltraGrid). If you are using DataTabael (DataSet) for the underlying data source you could set AllowDbNull property of the corresponding DataCoumn to False. Another option is to handle BeforRowDeactivate event of UltraGrid and to cancel the event if the customer doesn’t enter a value for that cell, please see attached sample.

I am waiting for your feedback
