We could include an option for the RadMultiColumnComboBox to behave similarly to an editable and read-only RadComboBox.

Currently, when a RadMultiColumnComboBox is placed in a ScrollViewer, the inner ScrollViewer of RadMultiColumnComboBox prevents the parent one from scrolling via the mouse wheel.

Add an option or change the default behavior and allow the scrolling to bubble to the parent scrollbar. This behavior can be observed in the native TextBox control with an enabled vertical scrollbar.

For the time being, the MouseWheel event can be manually raised:
private void ScrollViewer_PreviewMouseWheel(object sender, MouseWheelEventArgs e)
{
	if (sender is ListBox && !e.Handled)
        {
		e.Handled = true;
		var eventArg = new MouseWheelEventArgs(e.MouseDevice, e.Timestamp, e.Delta);
		eventArg.RoutedEvent = UIElement.MouseWheelEvent;
		eventArg.Source = sender;
		var parent = ((Control)sender).Parent as UIElement;
		parent.RaiseEvent(eventArg);
	}
}

Currently, when DataContext of RadMultiColumnComboBox changes to an object that contains valid SelectedItem and ItemsSource view model properties, the SelectedItem get set to null. This happens because the control resets the selection on ItemsSource changed, which happens after the SelectedItem binding was evaluated. 

Add an option to ensure that the SelectedItem won't get reset after the binding was evaluated  because of the ItemsSource changed action. The behavior should mimic how RadComboBox behaves in this scenario.

Remove the possibility for one or more rows to be searched on.

In other words, it should not be possible to select disabled item rows by search.

Currently the search text is cleared after a selection is made in the RadMultiColumnComboBox. We can provide an option to avoid this and keep the entered text after the selection is made.

It would be usefull to have a Property on the RadMultiColumnComboBox which represents the inputted searchtext. This Property should be TwoWay-Bindable.

A usecase for it could be to programmatically manipulate the searchtext.
For example setting it to NULL on LostFocus:

private void mccb_LostFocus(object sender, RoutedEventArgs e)
{
    this.mccb.ChildrenOfType<RadWatermarkTextBox>().First().Text = string.Empty;
}

Instead of hacking around with the visualTree etc. one could simply bind the property. This would also be MVVM compliant.

Proposed Name for the Property "SearchText".

 Expose DropDownOpened and DropDownClosed events similarly to the RadComboBox control.

The RadMultiColumnComboBox has a separate keyboard functionality executed when the watermark textbox (the search box) is focused and the dropdown is open. Basically, you can navigate through the rows of the gridview part and select them using the keyboard. 

Currently, this functionality is private. Introduce an API that allows you to customize the keyboard navigation. Consider something similar to the KeyboardCommandProvider of RadGridView.

Add a button that allows you to clear all the selected items.
