[RESOLVED] [2005] Validate Datagridview data

[campster]

I have a column in a DGV that contains directories. When the user enters a directory, I want to validate the directory before I allow the user to continue. Currently, I'm trying to use the CellLeave event to handle this and everything works if I modify an exsiting row. If I enter an invalid directory in a new row and choose to not accept the change, I get an index out of range error.

I know that the problem is with the canceledit butI can't think of another way to do this. Any ideas?

Private Sub dgvFiles_CellLeave(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dgvFiles.CellLeave
        Dim strDir As String
        Dim strWarn As String
        Dim strTitle As String
 
        If dgvFiles.Rows(e.RowIndex).IsNewRow Then Return
 
        strDir = CStr(dgvFiles.Rows(e.RowIndex).Cells("dir").EditedFormattedValue)
        strWarn = strDir & " is not a valid directory." & vbCrLf & _
                  "Do you want to retain this directory Value?"
        strTitle = "Invalid Directory"
 
        If Not Directory.Exists(strDir) Then
            If MessageBox.Show(strWarn, strTitle, MessageBoxButtons.YesNo, _
               MessageBoxIcon.Warning, MessageBoxDefaultButton.Button2) _
               = Windows.Forms.DialogResult.No Then
                dgvFiles.CancelEdit()
            End If
        End If
    End Sub
