Currently, the RadMultiColumnComboBox control does not support the ValidationErrorTemplateHelper.DisplayMode attached property. We could add support for it.

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.

Release R3 2020
RadGridView columns expose a IsSearchable property that is not taken into account when you use RadMultiColumnComboBox and search via the autocomplete box. Add support for the property. If set to False, the searching should not find the corresponding column.

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".

the multicolumncombobox has this weird display with X buttons which is completely inconsistent with a combo box.  Potentially make sense when you are multi-selecting but single select I would like to operate in the same way as a rad combo box so the user doesn't see any difference.

 Expose DropDownOpened and DropDownClosed events similarly to the RadComboBox control.
Unplanned
Last Updated: 07 Mar 2019 09:32 by ADMIN

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.

Expose a property to enable styling of the drop down element of MultiColumnComboBox. It the default scenario this is RadGridView.

Currently, an implicit style targeting RadGridView can be used instead.

the display of the drop-down part of the multicolumncombobox is different from the RAD combo box. There is an extra line between the content of the combo box and the drop-down button in the office 2016 theme at least. This should not be there to be consistent with the other combo boxes.
