Sure. It's of course not directly in the DataGridViewCellEventArgs, but 1 it's easily obtainable. In your event handler:

DataGridView dgv = (DataGridView)sender;
string columnName = dgv.Columns[e.ColumnIndex].Name;

if (e.ColumnIndex == dgv.Columns["CustomerName"].Index )
    and so on....

The answers above works great but if you 5 have to reference cell index a lot then 4 I will just add private int members to the 3 form, name them "idxMeaningfulColumnNameHere", then 2 initialize these members in Form's constructor. I 1 found it much easier this way.

Here is a custom method to be added to your 1 DGV.

Friend Function getColumnIndexByName(ByRef dgv As DataGridView, ByRef colName As String) As Integer
    For Each column As DataGridViewColumn In dgv.Columns
        If column.Name = colName Then Return column.Index
        Throw New Exception("Column Name not Found")
    Catch ex As Exception
        MessageBox.Show(colName & ": " + ex.Message)
    End Try
    Return -1
End Function

With that you can do something like:

If dgv1.getColumnIndexByName("SOME_COLUMN_NAME") = e.ColumnIndex Then Do_something()
