It's possibile to insert expansion indicator on columns header? Have columns grouped and having the possibility to hide/show in horizontal layout:
A+ B+ C+ -------> for example clicking on + near A and B obtains -------> A a1 a2 a3 B b1 b2 C+
No, there is no built-in functionality for this kind of thing. You should Submit a feature request to Infragistics.
You might be able to implement something like this yourself. You could use a CreationFilter to add the ExpansionIndicator or a button or something into the column header. Then you could hide or show certain columns based on the state of that ExpansionIndicator.
Ok, i used CreationFilter to add a button on column header to perform hide/show of other columns, and it works fine. But now I noticed that filtering and fixed column indicator don't work more, on the column where button is added. If i press on filter or fixed indicator in column header, the sorting is performed. Is it possibile to keep/preserve also these features?
thanks
