[2005] Validating DataGridView's cell

Hi,

How can I valide value in DataGridViews cell? I was trying to do it like that:

VB Code:

Private Sub DataGridView1_CellValidating(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellValidatingEventArgs) Handles DataGridView1.CellValidating
    
        If Me.DataGridView1.CurrentCellAddress.X = 1 Then
            If Not IsNumeric(Me.DataGridView1.CurrentCell.Value) Then
                e.Cancel = True
                MessageBox.Show("cell contains wrong value")
            End If
        End If
    End Sub

But this code returns error regardless of value that was entered into cell.

Please help,

You should be using the properties of the 'e' argument, i.e. e.ColumnIndex and e.FormattedValue.

Thanks jmcilhinney for your reply. But I have another problem: how can I avoid validating cell it isn't containing any value. I was trying to use such a code:

VB Code:

Private Sub dgvkryt_CellValidating(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellValidatingEventArgs) Handles dgvkryt.CellValidating
        Dim wartosc As Integer
 
        If e.ColumnIndex = 6 Then
 
            If IsDBNull(Me.dgvkryt.Rows(e.RowIndex).Cells("lp").Value) Then
                Exit Sub
            End If
 
            If Me.dgvkryt.Rows(e.RowIndex).Cells("lp").Value = "" Then
                Exit Sub
            End If
 
            If Not Integer.TryParse(e.FormattedValue.ToString, wartosc) _
            Or wartosc < 0 Then
                e.Cancel = True
                MessageBox.Show("wrong value", "error", _
                 MessageBoxButtons.OK, MessageBoxIcon.Error)
            End If
        End If
 
    End Sub

I was trying to check value using:

VB Code:

If IsDBNull(Me.dgvkryt.Rows(e.RowIndex).Cells("lp").Value) Then
                Exit Sub
            End If
 
            If Me.dgvkryt.Rows(e.RowIndex).Cells("lp").Value = "" Then
                Exit Sub
            End If

Unfortuantely when I insert value to cell and I go to another cell, previous cell is not validating. Only when I come back to this cell. Whats more I would like to stop validating when I delete content of cell.

Please help,
