I keep getting the error message:

"Index was out of range. Must be non-negative and less that the size of the collection".

What's weird is...I do the exact same thing with several other DGV's and no problems there. Anyway, here is my code:
Code:
    grd3.DataSource = dsAttachments.Tables(0).Rows
    FormatGrid3()
    '
    '
    '
    Private Sub FormatGrid3()
        Try
            grd3.RowHeadersVisible = False

            grd3.Columns(0).Width = 100
            grd3.Columns(0).HeaderText = "Request ID"

            grd3.Columns(1).Width = 140
            grd3.Columns(1).HeaderText = "Image Name"

            grd3.Columns(2).Width = 430
            grd3.Columns(2).HeaderText = "File Path"

        Catch ex As Exception
            strProcedure = "FormatGrid3()"
            Msg = ex.Message
            ErrorHandler(strModule, strProcedure, Msg)
        End Try
    End Sub
This error message occurs on the 1st line of the FormatGrid3() Sub and I just can't figure out what's causing it. I've compared the grid with other grids in my app and they're exactly the same...properties and all.

Thanks,
