When the ComboBox is placed inside a modal popup, the dropdown can't be closed on WinUI when clicking outside.

If you place an editable ComboBox in a TabView, its DropDown will not close when switching tabs. Just click into the ComboBox input to select an item and navigate to a different tab - the options list stays open.

Release 6.6.0
If a RadComboBox is used as an ItemTemplate for a ListView or CollectionView on MacCatalyst, the application crashes every time you attempt to open the dropdown with the following exception:

System.InvalidOperationException: Event registration is overwriting existing delegate. Either just use events or your own delegate: Microsoft.Maui.Controls.Handlers.Items.ReorderableItemsViewDelegator`2[Microsoft.Maui.Controls.ReorderableItemsView,Microsoft.Maui.Controls.Handlers.Items.ReorderableItemsViewController`1[Microsoft.Maui.Controls.ReorderableItemsView]] UIKit.UIScrollView+_UIScrollViewDelegate

Null Reference exception is thrown when using Native embedding.

When you add Telerik .NET MAUI controls that use icons, such as ComboBox, AutoComplete, etc, there are font-related exceptions in the output.

Although the exceptions do not affect the behavior and appearance of the controls, they make the output hard to read.

If a "long" placeholder value is set when the user selects a few of the items from the multi-select combobox and taps off of the combobox, the combobox is left displaying extra whitespace below.

Release 5.0.0

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.

The width of RadEntry, RadMaskedEntry, and RadComboBox are the same on windows, android and ios. On mac there is difference when the width of the defined Column is set to * in grid:

Whenever the combobox doesn't have enough space to be displayed on the screen, the footer gets pushed to the bottom and off the dropdown popup.

This was tested on Telerik 3.0 but I also tested it on 3.1, 3.2, 3.2.1, and 4.0 with the same results.

Setting the IsEnabled property of the RadComboBox component to false makes it appear as grayed out, but the user is still able to select a value from the drop-down.

Release 3.2.0

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.

It appears that by the amount of problems that I have encountered so far that Telerik UI for .NET MAUI has not been tested at all on IOS.

Your own ControlSamples do not run for IOS.


Next problem.

IOS Specific only.

           <telerik:RadComboBox ItemsSource="{Binding Items}"
                                     Placeholder="Select Status"

note that to use the Telerik Custom Controls it is necessary to either add an x:name to each control, or dummy instantiate each one.

This can be done in MauiProgram.cs.

Add line

  _ = new RadComboBox();


A runtime error occurs when using telerik:RadComboBox and the application will abort.

When there are multiple ComboBox controls on the screen with IsEditable set to "True". After clicking the combo or typing a keyword the cursor starts blinking as the focus gets stolen. This freezes the application and requires it to be restarted.
