Using the RadComboBox for the first time, I first implemented it on a test page to ensure I figured out how to implement it properly. After a little trial & error, I got it working, displaying 2 columns of a DataTable as is shown in the first attachment.
Now I'm trying to implement it for real, which happens to be in a RadWindow dialog box. Yet, as the 2nd attachment shows, it's not populating in the same way. Not only does it only have just one column, but even the basic appearance of the collapsed RadComboBox is different:
- In the test case it appeared grey in colour
- In the RadWindow it appears white in colour, indistinguishable from the standard DropDown ListBox
What do I need to do with the RadWindow implementation to get it to populate correctly?
