RadComboBox for .NET MAUI has search feature, however it does not filters the items matching the text, instead it only scrolls to the matching item. We can manually filter the items in the item source but it would be nice to have such filtering built in.

Also we need to highlight the first item that matches the search string. Currently it doesn't seem to be possible. One way could be to select the first item manually which may change the background of the item and give a feel of highlight but that causes problem with selected item because we also need to subscribe to selected item change and do some other processing based on that. If we select item as filter happens then it would trigger selection change multiple times needlessly.

Also it seems that currently RadComboBox dropdown does not have support for keyboard navigation. We need to be able to navigate between items with keyboard up/down arrows so that user can navigate to different items and then press enter to select the highlighted item. This feature might not make sense on mobile but it is needed for desktop platforms.

Let me know if there is already a way to achieve the above behavior.

It would be nice to have the ability to select different item in the dropdown by keyboard up/down arrows.

We would like to be able to override the behavior of the Clear button in the editable combo box.

When the user has started typing into an editable combo box, and they click the Clear button before they've selected another item, we want to revert their text to what was in there before they started typing and keep the previously selected item selected, rather than clearing the text and selected item.

If you can add that functionality, even better, but it should be enough to just expose the Clear button's Click event (with a Cancel param or another way to ensure the text isn't cleared), so we can override the current functionality.

Provide an option to modify the ComboBox so there is no space between the ComboBox and the dropdown.

Reduce the space between the text and the X button.

I want to reset the scroll position because in our implementation, we have filter buttons that when clicked, fetch a new list from our web API. 

It appears that the scroll position is being saved when a new list is assigned while the ComboBox is not focused.

When setting SelectedItem and using static data for the ItemsSource, Layout cycle detected. Layout could not complete exception is thrown
Setup:

<telerik:RadComboBox x:Name="ComboBox" 
                                 SelectedItem="{Binding SelectedItem, Mode=TwoWay}">
                <telerik:RadComboBox.ItemsSource>
                    <x:Array Type="{x:Type x:String}">
                        <x:String>USA</x:String>
                        <x:String>Uganda</x:String>
                        <x:String>Ukraine</x:String>
                        <x:String>Canada</x:String>
                        <x:String>France</x:String>
                        <x:String>Italy</x:String>
                        <x:String>United Kingdom</x:String>
                        <x:String>China</x:String>
                        <x:String>Japan</x:String>
                    </x:Array>
                </telerik:RadComboBox.ItemsSource>
            </telerik:RadComboBox>

Telerik RadComboBox for MAUI looses focus and triggers unfocus event after selecting an item from the dropdown. This behavior works fine on first time page loading. But if we navigate to some other page and then navigate back to the first page then, upon selecting any item from combobox it closes the dropdown but does not loose the focus and hence does not trigger unfocus event.

We are using the unfocus event with event to command behaviour and ultimately triggering a command in viewmodel. This works fine the first time but after navigation it does not work.
