Hi,
Happy new year 2009 to everybody !
I'm experiencing an issue with Visual studio 2008 ans Ultracombo's datasource.
I've made a sample program to reproduce the problem.
Here's the example :
ObjectA is composed of a list of ObjectB.
If you set ObjectA as datasource of Ultracombo it will works, but now if you edit ObjectB and add a reference to ObjectA (uncomment my line) then Visual Studio will hang/freezes until you kill the process when trying to edit the combo or execute the program.
It seems that Infragistics controls doesn't like recursive calls within a datasource as it seems to add the Object B properties as columns for the UltraCombo ? (so A call B which call again A, then B, ....)
I don't know what to do as I need to be able to set A as datasource in my combo to display some of the columns and hide the others.
How doest Ultracombo datasource works ? How can i by the way add a second band in the same combo with a datasource ?
Please advice !

(if even possible !)

If you want to simulate "manually" adding items to WinCombo (as opposed to WinComboEditor), use a DataTable or a WinDataSource to which you add the items you want shown in the control.
Thanks for your anwser,
