[Solved] Cell Changed and validation issue

[Extra]

Hi all,

I am now facing a problems on DataGrid cell changed issue, my grid have some fields while column A is Parts Code, and column B is Parts Name.

I want to set a function that when the user input some value in column A, it will check if column A is a valid parts code by using ria service.

If yes, it will get the part name from the checking ria service and put it in column B. If not, it will prompt error message in cell validating checking.

How can I perform this task? I tried to put this logic (check part A is valid or not ) into the cell validating checking. but seem not working

Thank you very much

Hello Extra,

 Can you clarify if this is the standard Silverlight DataGrid or Telerik RadGridView?

Oops, my fault. I am using telerik RadgridView Thanks for your reply

Hello,

 It will be better to handle such cases at data level using properties setters directly and/or DataAnnotations. The grid will handle them automatically. 

All the best,
