The following code example demonstrates using CellMouseEnter and CellMouseLeave event handlers to determine whether a cell can be clicked. The example updates each ToolTipText property value to advertise the current image layout. This code is part of a larger example shown in How to: Work with Image Columns in the Windows Forms DataGridView Control.

Private Sub dataGridView1_CellMouseEnter(ByVal sender As Object, _
    ByVal e As DataGridViewCellEventArgs) _
    Handles dataGridView1.CellMouseEnter

    Dim markingUnderMouse As Bitmap = _
        CType(dataGridView1.Rows(e.RowIndex). _
            Cells(e.ColumnIndex).Value, Bitmap)

    If markingUnderMouse Is blank Then
        dataGridView1.Cursor = Cursors.Default
    ElseIf markingUnderMouse Is o OrElse markingUnderMouse Is x Then
        dataGridView1.Cursor = Cursors.No
        ToolTip(e)
    End If
End Sub

Private Sub ToolTip( _
    ByVal e As DataGridViewCellEventArgs)

    Dim cell As DataGridViewImageCell = _
        CType(dataGridView1.Rows(e.RowIndex). _
        Cells(e.ColumnIndex), DataGridViewImageCell)
    Dim imageColumn As DataGridViewImageColumn = _
        CType(dataGridView1.Columns(cell.ColumnIndex), _
        DataGridViewImageColumn)

    cell.ToolTipText = imageColumn.Description
End Sub

Private Sub dataGridView1_CellMouseLeave(ByVal sender As Object, _
    ByVal e As DataGridViewCellEventArgs) _
    Handles dataGridView1.CellMouseLeave

    dataGridView1.Cursor = Cursors.Default
End Sub
