i found a bug similar to forum post, but not the same.
In MultiColumnComboBox when SelectionBoxesVisibility is set to 'collapsed' and and whatever you set AutoCompleteMode to (different from the forum post),
if you select the first item it is not shown. Although the NullText is removed. It works perfectly for all the other items. This is quiet a problem if you only have one item in the dropwdown :D
If set the AutoCompleteMode property in a Style Setter, and exception is thrown.
To work this around set the property directly on the control.
<telerik:RadMultiColumnComboBox AutoCompleteMode="Search" />
Exception is thrown after typing in the autocompletebox and selecting an item right after that.
Thanks in advance.
The event should fire when the DropDownContentManager gets initialized.
To work this around use the InitializeSelectionBridge event. The DropDownContentManager is initialized when this event fires.
when selecting more items and dropdown positioning is down and input filed has fixed width, the dropdown covers the input field.
It should move down to the bottom edge of input field.
