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

 Expose DropDownOpened and DropDownClosed events similarly to the RadComboBox control.

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.

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

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.

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.

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.

Release LIB 2020.1.210 (02/10/2020)

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).
