Hi,
I have one datagridview, in that the first column contains auto-complete, the auto-complete contains name which come from the database so i want to show related other values into datagridview of next column by using c# windows application.

For ex: suppose i select the name "abc" the related value of abc means mobile no,address shown in the next column of datagridview.

Thanks in advance.
