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 void dataGridView1_CellMouseEnter(object sender,
    DataGridViewCellEventArgs e)
{
    Bitmap markingUnderMouse = (Bitmap)dataGridView1.
           Rows[e.RowIndex].
           Cells[e.ColumnIndex].Value;

    if (markingUnderMouse == blank)
    {
        dataGridView1.Cursor = Cursors.Default;
    }
    else if (markingUnderMouse == o || markingUnderMouse == x)
    {
        dataGridView1.Cursor = Cursors.No;
        ToolTip(e, true);
    }
}

private void ToolTip(DataGridViewCellEventArgs e, bool showTip)
{
    DataGridViewImageCell cell = (DataGridViewImageCell)
        dataGridView1
        .Rows[e.RowIndex].Cells[e.ColumnIndex];
    DataGridViewImageColumn imageColumn =
        (DataGridViewImageColumn)
        dataGridView1.Columns[cell.ColumnIndex];

    if (showTip) cell.ToolTipText = imageColumn.Description;
    else { cell.ToolTipText = String.Empty; }
}

private void dataGridView1_CellMouseLeave(object sender,
    DataGridViewCellEventArgs e)
{
    ToolTip(e, false);
    dataGridView1.Cursor = Cursors.Default;
}
