Hi,

I have a Grid where I need to implement a ICustomSummaryCalculator for special calculation of a sum.

Now I want to appear the SummarySelection in the ColumnHeader (the sigma-sign) to let the user select if he wants to see the summary or not.

Now I have the problem, that the SummarySelection-Dialog, which appears when I click on the Sigma-sign, does not contain my summary. It only contains sum, count, average, ...

How can I achieve to get my calculation method to appear in this dialog?

Much better would be to be able to override the method, when the user clicks on "sum", so I am able to define what "sum" means. Is that possible, too?

Kind regards,

Wolfgang
