Create a combo box control that supports multi selecting, like the WPF version e.g.

https://docs.telerik.com/devtools/wpf/controls/radcombobox/features/multiple-selection

Hello,

I have Telerik.WinUI.Controls v4.0.0 installed with Telerik.Licensing v1.6.5 with the extension installed and the license text file in the root folder of my project. However, I receive this message the first time a RadDataGrid is loaded on the UI on a secondary window. After closing and re-opening the window, the message doesn't show. When packaging for release, this doesn't seem to be an issue. The message is also stating the wrong version.

Since Q2 2025, user defined Dark/Light/HighContrastResourcesPaths do not work - the custom resources are anot applied to the controls.

/// <summary>
/// Resource loader that provides the resource dictionaries with the brushes for the Telerik controls.
/// See https://docs.telerik.com/devtools/universal-windows-platform/common/teleriknamedbrushes.
/// </summary>
public sealed class TelerikResourceLoader : CustomXamlResourceLoader
{
    /// <inheritdoc/>
    protected override object GetResource(string resourceId, string objectType, string propertyName, string propertyType)
    {
        object result;
        if (resourceId == "DarkResourcesPath")
        {
            result = new Uri("ms-appx:///{ProjectName}/Assets/Themes/Dark_Telerik.xaml");
        }
        else if (
            resourceId == "LightResourcesPath" ||
            resourceId == "HighContrastResourcesPath")
        {
            result = new Uri("ms-appx:///{ProjectName}/Assets/Themes/Light_Telerik.xaml");
        }
        else
        {
            result = null;
        }
        return result;
    }
}

<ResourceDictionary.ThemeDictionaries>
    <ResourceDictionary x:Key="Light">
        <SolidColorBrush x:Key="TelerikGrid_BackgroundPointerOver" Color="Red" Opacity="0.25"/>
    </ResourceDictionary>
    <ResourceDictionary x:Key="Dark">
        <SolidColorBrush x:Key="TelerikGrid_BackgroundPointerOver" Color="Green" Opacity="0.25"/>
    </ResourceDictionary>
</ResourceDictionary.ThemeDictionaries>

Edit - indeed the Light/Dark/ResourcePaths are deleted from the generic files of telerk controls due to the following regression in WinUI App SDK 1.7.25:

Hello,

when I create a ContentDialog (or Popup) containing a RadDataGrid, row/cell selection doesn't work. It seems like all pointer events are ignored on the cells panel. Here is the sample code:

using Microsoft.UI.Xaml;
using Microsoft.UI.Xaml.Controls;
using Telerik.UI.Xaml.Controls.Grid;

namespace GridTest
{
    /// <summary>
    /// An empty window that can be used on its own or navigated to within a Frame.
    /// </summary>
    public sealed partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            ContentDialog contentDialog = new ContentDialog()
            {
                Content = new RadDataGrid()
                {
                    ItemsSource = new DummyData[] { new DummyData("Item 1") }
                }
            };

            contentDialog.XamlRoot = this.Content.XamlRoot;
            contentDialog.ShowAsync();
        }
    }

    public record DummyData(string Text);
}

Could you please fix this as soon as possible or provide me a workaround for this bug

Greetings

I have bought a licence and am trying to update my project to use the licenced nuget packages instead of the trial ones. The problem is that I am only able to see the trial packages in the nuget package explorer.

I have run the installer and added https://nuget.telerik.com/v3/index.json as the nuget source. I know that at some point when I first added a package I filled in my credentials, because of reasons the licenced version is tied to another account, if this could have anything to do with it.
