Hi recently started to work my .net maui apps in NET - 8 on iOs, but i having a problem with telerik i can't even load any view with a telerik component, instead I got this error:

Excepción no controlada del tipo 'System.Exception' en Microsoft.iOS.dll: 'Could not create an native instance of the type 'TelerikUI.TKWeakReference': the native class hasn't been loaded.
It is possible to ignore this condition by setting ObjCRuntime.Class.ThrowOnInitFailure to false.'
<No se puede evaluar el seguimiento de la pila de excepciones>

I can't find any info related o similar cases, what can i do?

I don't have this problem in android it only happens in iOS, I'm using NET 8.0 and Telerik 6.5.0 version

RadComboBox and RadDatePicker drop-downs not opening correctly within a popup window on iOS

I've noticed that when I use a RadComboBox or RadDatePicker within a Popup window on iOS that the dropdown displays outside of the popup window and therefore not able to click and choose options within the dropdown. I have created a basic program that shows the problem. I'm running it on an iPad simulator running iOS 17.5. Sometimes, I can adjust the vertical offset to get it to display within the popup, but it would be better if it displayed just below the control.

[Solved] RadListView and PropertySortDescriptor

Using the example from: https://docs.telerik.com/devtools/maui/controls/listview/sorting#propertysortdescriptor

I am having issues adding a PropertySortDescriptor to ObservableCollection<SortDescriptorBase> without getting a type error.

I have tried playing around with things and I just can't seem to get it working based on the reference I have. Any ideas? I have tried using listView.SortDescriptors.Add without luck... I have tried binding it to a collection per the docks to no avail, and I've tried to move the types around to see if I can get a better result... nothing seems to work?

        _radListViewModel.SortDescriptors.Add(new PropertySortDescriptor() { PropertyName = "PickupNumber", SortOrder = SortOrder.Ascending }); // Conversion Error
        listView.SortDescriptors.Add(new PropertySortDescriptor() { PropertyName = "SchedArriveEarly", SortOrder = SortOrder.Ascending }); // Conversion Error
        listView.SortDescriptors.Add(new Telerik.Maui.Controls.Compatibility.DataControls.ListView.SortDescriptorBase() { PropertyName = "PickupNumber", SortOrder = SortOrder.Ascending }); // Error, its a type and cannot be used to create an instance

Grouped CollectionView visible

Hi!

I migrated from Listview to Collectionview and I have 2 problems.
Can you help me?
1- Is it possible to hide the group indicator?
2- This blank space appears at the end of the layout. In the Listview everything is ok, but in the CollectionView I couldn't identify it. Do you know what it could be?

RadTabView is not showing the content when making a tab visible dynamically through property binding - IOS

Hi Team,

The following issue exists in IOS.

I have a page where using RadTabView, Initially when opened the page we show 4 tabs by default and the 5th one is hidden, on a button click we do IsVisible = true & IsSelected = true for the 5th tab, but the 5th tab is not getting visible in IOS whereas it is getting selected (tab name is highlighting which indicates that it is selected).

For the first 4 tabs also we are binding the IsVisible with one property, If we hide that while making the 5th tab visible then the 5th tab is being visible.

The same code works fine in IOS.

Thanks,

Mohammed Rameez Raza (Rameez).

RadDataGrid Tab order (items/row index order) skipping!

Hello,

Using .NET MAUI to develop a Windows desktop application.

I have a page where a RadDataGrid gets populated with a list of items.

The columns are:
Column 1 = telerik:DataGridTextColumn

Column 2= telerik:RadNumericInput (usingtelerik:DataGridTemplateColumn)

My client reported an overlooked issue, and I confirm that when using "tab" to go to the next editable cell, which in my case is the next row, it does NOT follow the sequence of the items...

Example:
Clicked on the first item to focus, from item/row 1 goes to 2, then 3 (so far so good) but all the sudden the next focus goes all the way to item/row 11 or something then after that seems to follow a random order which defeats the purpose of using the tab functionality.

For clarification, I am using enter as 'Tab' by implementing a style to the telerik:RadEntry with a
"<Setter Property="ReturnType" Value="Next" />". However, the same behavior happens using the 'Tab' key.

Video of the issue attached

A fix, observation or any workaround would be greatly appreciated!!

[Solved] Customize color of Selection Indicator from NavigationItemView

Hi team,

I am wondering how to customize the color of the selection indicator, the small vertical colored bar that appears when an item in the Navigation control is selected.

The current color seems to be the accent color of the device, for example, on Windows, the accent color from the theme Windows customization.

I tried to change the BackgroundColor on the NavigationViewItemView, but that doesn't work for the small indicator.

In your project sample, the small menu where you can select "First look," "Configuration," etc., is built with a telerik:NonVirtualizedItemsControl.

And this control have that style targetted telerik:NonVirtualizedItemsControlItemContainer

And THAT change the indicator for the selected item like I need for the Navigation Controle.

My question is how to change the color of that indicator ?
