The following error is thrown when the dropdown of the control is opened: Cannot find governing FrameworkElement or FrameworkContentElement for target element. ... ; target element is 'GridViewItemsSourceProvider; target property is 'ItemsSource' (type 'Object')

If the combobox is placed inside a RadGridView, the error is thrown each time the dropdown is opened (after a commit action).

Hi Telerik-Team,

 

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

 

Regards,

Mats

The selection is lost when sorting or filtering is applied and the control is already filtered.

Release LIB 2019.2.805 (8/05/2019)

If set the AutoCompleteMode property in a Style Setter, and exception is thrown.

To work this around set the property directly on the control.

Create API which can change the selected item when only using the Up/Down keys of the keyboard.

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.

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.
Approved
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.

If you set the SelectionMode of the control to Multiple the SelectionChanged event fires only when you select item for the first item. Each next selection won't fire the event.

To work this around use to CollectionChanged event of the SelectedItems collection of RadMultiColumnComboBox.

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.
