Join Bytes to post your question to a community of 473,405 software developers and data experts.

Form datagrid --- get the sum of the column

we let user enter data in one column of the datagrid and would like to get
the sum while data is entering.
I tried to capture different events(TextChanged, KeyUp, etc) and do the sum
in the event handlers, but none of them will include the current data that
user is entering.

any suggestions?

Thanks a lot.
