Add grouping support in the GridView element.

GridViewMultiColumnComboBoxColumn does not have any selected value in edit mode when SelectionBoxesVisibility is set to Collapsed/Hidden and AutoCompleteMode is Search/Suggest.

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" />

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.

 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.

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.

Hello Telerik,

Exception is thrown after typing in the autocompletebox and selecting an item right after that. 

Thanks in advance.

 

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.

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.

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.

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.

Hello,

 

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.

 

Add option to hide row indicator in grid.

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

 

Hello,

 

Add non-editable feature to MultiColumnComboBox ( like on ComboBox ).

 

Thx,

Tino.
