Hi
Hope the below expression would help you get the column name
For AA1, AA2, AA3,……
Same with a little change in expression
Convert.ToChar( (65 + dt.Columns.IndexOf("Columnname") ) - 26).ToString + (dt.Rows.IndexOf(CurrentRow)+2).ToString
(Output will be “AA1”, “AA2”,…. String type)
Refer this thread for complete details
