sort symbol in column header not showing correctly

[Hermann]

Good morning,

I'm using the RadDataGrid control from 'UI for Windows Universal'.
When clicking on a column header, the rows are correctly sorted, but the sort symbol that shows up next to the header name is not showing correctly.

By inspecting that symbol with 'Live Visual Tree' I can see it's a TextBlock with FontFamily set to 'Segoe MDL2 Assets'.
By changing that to 'Segoe UI Symbol' in the 'Live Property Explorer', the symbol shows correctly (a black triangle).

I attached a screenshot that shows the issue.

 Here is some code to reproduce the issue.

<Page
    x:Class="RadDataGridTest.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:RadDataGridTest"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:grid="using:Telerik.UI.Xaml.Controls.Grid"
    xmlns:core="using:Telerik.Data.Core"
    mc:Ignorable="d"
    Name="Self">

    <Grid>
        <grid:RadDataGrid
            AutoGenerateColumns="True"
            ItemsSource="{Binding ElementName=Self, Path=Items}"/>
    </Grid>
</Page>

 

 

public sealed partial class MainPage : Page
{
    public MainPage()
    {
        this.InitializeComponent();
    }

    public List<Item> Items
    {
        get
        {
            return new List<Item>
            {
                new Item { Field = "Bravo" },
                new Item { Field = "Alpha" },
                new Item { Field = "Charlie" }
            };
        }
    }
}

public class Item
{
    public string Field { get; set; }
}

 

How can I fix this issue?

Thank you for your help.

Hello,

We are aware of this issue and it will be fixed for our next release. Currently the only way to change the FontFamily of this TextBlock is to get the template of the DataGridColumnHeader  ​control from our source code and set it manually.

Sorry for any inconvenience caused.
