Mouse hover DataGridView

[jpinto]

Hello,

I want to change the cursor type when the mouse goes over a certain column in a dataview. I've the following code:

Private Sub DataGridView1_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles DataGridView1.MouseHover
        If DataGridView1.CurrentCell.ColumnIndex = 7 Then
            DataGridView1.Cursor = Cursors.Help
        Else
            DataGridView1.Cursor = Cursors.Default
        End If
    End Sub

The problem is that when entering the DataView, the cursors goes over the headers and I receive an error because there is no CurrentCell!
Can annyone help me please?

Thanks,

João Pinto

How about:

Private Sub DataGridView1_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles DataGridView1.MouseHover

[red]If DataGridView1.CurrentCell Is Nothing Then Return[/red]

If DataGridView1.CurrentCell.ColumnIndex = 7 Then
DataGridView1.Cursor = Cursors.Help
Else
DataGridView1.Cursor = Cursors.Default
End If
End Sub

Ack multiple exit points!

Private Sub DataGridView1_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles DataGridView1.MouseHover

    If not DataGridView1.CurrentCell Is Nothing Then 
        If DataGridView1.CurrentCell.ColumnIndex = 7 Then
            DataGridView1.Cursor = Cursors.Help
        Else
            DataGridView1.Cursor = Cursors.Default
        End If
