When a monospace font is applied to cells, the cell content does not align as expected. Instead of maintaining consistent horizontal alignment typical of monospace typefaces (where each character occupies equal width), the text appears misaligned or uneven across cells.

I have been trying to get the DataGrid to work with Maui.Markup and I'm not finding a way to add a DataGrid to my View.
I would have expected I could add a DataGrid to the Children of Grid...but I'm not finding the right cast to allow that to happen, Grid.Children is expecting an IView.
Is this possible and I'm just missing something simple? Thanks!

</Grid>On initial Refresh, all items are visible in the DataGrid
I navigate forward and then back (PopToRoot), the DataGrid appears empty, although the vertical scroll appears like there are items.
If I tap Refresh, items become visible, but only above the first fold.
If i resize the window vertically, items will appear and disappear depending on the height of the window. (see attached video)

Header Text, group header text, do not display some languages characters like Chinese, Thai, etc.
The root reason for this is the fact that the Skia APIs used to draw the text does not support automatic character fallback.
Workaround:
for header text:
<telerik:DataGridTextColumn.HeaderContentTemplate>
<DataTemplate>
<Label Text="your text"></Label>
</DataTemplate>
</telerik:DataGridTextColumn.HeaderContentTemplate>group header text
<telerik:RadDataGrid.GroupHeaderTemplate>
<DataTemplate>
<Label Text="{Binding Group.Key}"/>

</telerik:RadDataGrid.GroupHeaderTemplate>column:
<telerik:DataGridTextColumn HeaderText="Name" >

When the selected item is set initially, the selected style is not applied to the row/cell.
Workaround: You can use a Dispatcher to workaround the issue, code looks as follows:
this.Dispatcher.StartTimer(TimeSpan.FromMilliseconds(200), () =>
{
if (dataGrid.SelectedItem == null)
{
dataGrid.SelectItem(viewModel.PersonCollection.First());
}
return false;
});

When a Picker is used in a CellEditTemplate, and when in edit mode, when I click on the arrow of the Picker - the picker does not open. It only opens of I click the text in the Picker.
<DataTemplate x:Key="template1">
<Picker ItemsSource="{Binding Item.Categories}" />
</DataTemplate>
<telerik:RadDataGrid x:Name="dataGrid"
AutoGenerateColumns="False">
<telerik:RadDataGrid.Columns>
<telerik:DataGridTextColumn PropertyName="Name" />
<telerik:DataGridTextColumn PropertyName="Category" CellEditTemplate="{StaticResource template1}" />
</telerik:RadDataGrid.Columns>
</telerik:RadDataGrid>
A work-around is to not use a Picker, but use a RadComboBox.

Provide a style property for the text in grouping panel. Currently you can style the border, background color and change the header text of the panel. For example:
<Style TargetType="telerik:DataGridGroupingPanel">
<Setter Property="BackgroundColor" Value="Red"/>
<Setter Property="HeaderText" Value="Hello to group"/>
<Setter Property="CornerRadius" Value="10"/>
<Setter Property="BorderThickness" Value="2"/>
<Setter Property="BorderColor" Value="Blue"/>
</Style>
