It´s possible in the following example use the name of column instead the column number:

row.Cells(2).Text

for ex: like:

row.Cells("name").Text

yes you can do this.  In fact it's preferred because if you change your columns around programattically your indexes will all get messed up.

But when i try with this code i get an error message in msgbox() line :


    Protected Sub GridView1_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridView1.RowCommand

        If e.CommandName = "Add" Then
            Dim index As Integer = Convert.ToInt32(e.CommandArgument)
            Dim row As GridViewRow = GridView1.Rows(index)
            MsgBox(row.Cells("name").Text)
        End If

    End Sub


Error message:       
The conversion of the chain "name" to type 'Integer' is not valid.
