Hi Greycon,

There is a method on the ColumnHeader that we call to show this dialog. However, this method is internal so you will need reflection to get at it. Try the following code:

Infragistics.Win.UltraWinGrid.ColumnHeader header = ultraGrid1.DisplyLayout.Bands[0].Columns[0].Header;
MethodInfo methodInfo = typeof(Infragistics.Win.UltraWinGrid.ColumnHeader).GetMethod("OnClickSummaryRowsButton", BindingFlags.NonPublic | BindingFlags.Instance);
methodInfo.Invoke(header, new object[] { header.GetUIElement() });

Please let me know if you have any further questions.

Hi Mike,

Thank you for your reply. What I need is not to add summaries programmatically.
I need to open exactly the same infragistics form with all the options, but instead of opening it by pressing the (Σ) button I would like to open it from another custom pop up menu.

Ideally I wanted to hide the sigma button and handle its behavior from another right click menu that I have created. But as I understand the only way to do this is to create a custom form which will simulate the infragistics pop up form


Kind regards
