MultiColumnComboBox broken in 5.1 beta
Hello,
I have code that worked fine (and in fact was suggested by Syncfusion) under 4.x that is now broken under 5.1 beta.
In short, operations - called before the parent form is shown - involving a MultiColumnComboBox's ListBox will fail because the ListBox is null.
For example, a form contains only a MCCB. In the form's ctor after InitializeComponent(), trying to add an EventHandler to the MCCB's ListBox will fail because it is null.
However, if the EventHandler is added after the form is displayed (via the click handler of a button for example) no exception is thrown.
I've attached a small project that demonstrates this behavior.
Using 4.x there were no such problems.
Is this a bug or are we supposed to initialize the ListBox outselves somehow? Please advise.

Same thing has happened to us..
When we installed the new version our project will not compile..On my case it doesn't find
syncufision.windows.forms so nothing works..I added the dll to the toolbar so that it can generate everything and droped a control but it still wont recognize it..
