Blinking Tooltip

I am using a tooltip on a listbox and although it works it keeps flickering/blinking any idea's how to fix this? The only thing i could think of was turning on double buffering but that didn't work.

this is the function i use;

private void onMouseMove(object sender, MouseEventArgs e)
{
    if (sender is ListBox)
    {
        Point point = new Point(e.X, e.Y);
        int hoverIndex = LSB_OfflineVars.IndexFromPoint(point);
        if (hoverIndex >= 0 && hoverIndex < LSB_OfflineVars.Items.Count)
        {
            tt.SetToolTip(LSB_OfflineVars, LSB_OfflineVars.Items[hoverIndex].ToString());
        }
    }
}

Thanks in advance, Robin

you can also solve this by just adding tt.toolTip.Hide(dataGridCurrAlarms); tt.toolTip.RemoveAll(); at the beginning of the method

Using onMouseHover instead should resolve the issue as it will not be triggered as often but still provide the same functionality.

How about if you set the ShowAlways property to true.
