Data validation on row of DataGrid

[lisa.biagioni]

Hi,

I have a DataGrid bound to a DataTable in a Windows Forms application.
I'm using the DataTable.RowChanging event to trigger the validation of
a row when the user has modified a row and clicks off of it. The
problem is that there is no cancel on the RowChanging event. So, if
the validation on the row fails, how do you keep the pointer on the row
of the DataGrid where the error occurred?

Any help anyone could give me on this would be greatly appreciated!

Thanks in advance,

Lisa

Lisa - if you trap the CurrentCellChanged event

you can probably get what you need. You can also use Extended properties
for instance if your validation is simple to create a rule to validate
against. If I understand you correctly though, I think the
CurrentCellChanged event in conjunction with the specific column will get
you what you need.

HTH,

Bill
