Hi, I have a simple WinForm containing only a chart control. This Form is a Child of a MDI Form. When I use ChartForm.Show() for the first time no problem occurs. Now I'm hiding ChartForm in the FormClosing Event private void ChartForm_FormClosing(object sender, FormClosingEventArgs e) { if (e.CloseReason == CloseReason.UserClosing) { this.Hide(); e.Cancel = true; } } So far so good The next time I start ChartForm.Show() all tool-tips from the series are gone. It seem the GetTip-Event isn't fired anymore When I'm using ChartForm as a simple Form and not as a MDI-Child the problem doesn't occur. And now to something completely different Is it possible to assign one series or more to a CustomLegendItem. I have around twenty series, each four series have the same name. I want to bundle this four series in a group and highlight all when I hover over a CustomLegendItem. Regards Friedhelm
