RadWatermarkTextBox and EventToCommandBehavior

I'm trying to capture when the Enter key is pressed in a RadWatermarkTextBox without adding code to code-behind.

In the XAML I have:

            <telerik:RadWatermarkTextBox MinHeight="26"
                                         x:Name="searchCompleteBox"
                                         VerticalAlignment="Center"
                                         Text="{Binding SearchText, Mode=TwoWay}"
                                         Width="200" 
                                         WatermarkContent="Enter name, address, or ID">
                <telerik:EventToCommandBehavior.EventBindings>
                    <telerik:EventBinding Command="{Binding OnSearchCompleteBoxKeyDownCommand}"
                                     EventName="KeyDown"
                                     PassEventArgsToCommand="True" />
                </telerik:EventToCommandBehavior.EventBindings>
            </telerik:RadWatermarkTextBox>

In the ViewModel:

    private async void OnSearchCompleteBoxKeyDown(System.Windows.Input.KeyEventArgs e)
    {        
        if (e.Key == Key.Enter)
        {
            await SearchForMembersAsync();
        }
    }

The problem is SearchText is not updating. So if I type something like "smith" OnSearchCompleteBoxKeyDown fires five times, the if result is false five times, but SearchText contains an empty string instead of "smith".

SearchText is declared properly and is updated properly if I take the EventToCommandBehavior code out. This all works properly if I use code-behind but I want to avoid that.

RadCartesianChart Annotation Questions

Hello, I have two questions regarding the RadCartesianChart Annotations.

Question 1:

I have attached an example project to this question. When I first open the example project the text of the Annotation seems to be cut off. This fixes itself if the window is resized and the problem doesn't seem to occur again. Is there a way to not have this cut off text? Am I setting a property incorrectly?

Question 2:

In the same attached project I have one of the annotation labels set to the location bottom; however, I can't seem to find it in my window. Is there something I am missing to get this text to show up?

Here is the relevant xaml:

<telerik:RadCartesianChart Grid.Row="1" >

    <telerik:RadCartesianChart.Annotations>

        <telerik:CartesianGridLineAnnotation Value="20" Stroke="Red" FontSize="20" StrokeThickness="5" Axis="{Binding ElementName=horizontalAxis1}" Label="Example" Foreground="Black">
            <telerik:CartesianGridLineAnnotation.LabelDefinition>
                <telerik:ChartAnnotationLabelDefinition Location="Inside" HorizontalAlignment="Center" />
            </telerik:CartesianGridLineAnnotation.LabelDefinition>
        </telerik:CartesianGridLineAnnotation>

        <telerik:CartesianGridLineAnnotation Value="25" Stroke="Red" FontSize="20" StrokeThickness="5" Axis="{Binding ElementName=horizontalAxis1}" Label="Example" Foreground="Black">
            <telerik:CartesianGridLineAnnotation.LabelDefinition>
                <telerik:ChartAnnotationLabelDefinition Location="Inside" HorizontalAlignment="Center" />
            </telerik:CartesianGridLineAnnotation.LabelDefinition>
        </telerik:CartesianGridLineAnnotation>

        <telerik:CartesianGridLineAnnotation Value="30" Stroke="Red" FontSize="20" StrokeThickness="5" Axis="{Binding ElementName=horizontalAxis1}" Label="Example" Foreground="Black">
            <telerik:CartesianGridLineAnnotation.LabelDefinition>
                <telerik:ChartAnnotationLabelDefinition Location="Bottom" HorizontalAlignment="Center" />

RadGridView - Custom Filtering Controls for a list of viewmodels

Hi good morning, I need help with the design and how to implement a custom filter. If you can help me with a small example, I have been reading the "Custom Filtering Controls" documentation (https://docs.telerik.com/devtools/wpf/controls/radgridview/filtering/custom-filtering-controls) but I am having trouble implementing it for this case.

Currently I have a RadGridView, which shows a list of orders. One of the columns shows a list of icons:

public required List<IMvvmViewModel?> DesignStatusViewModels { get; set; }

Column:

<telerik:GridViewDataColumn IsReadOnly="True" HeaderCellStyle="{StaticResource DesignStatusCellStyle}">
<telerik:GridViewDataColumn.Header>
<TextBlock
Text="Design Status"
MinWidth="100"
Width="Auto"
TextAlignment="Center">
</TextBlock>
</telerik:GridViewDataColumn.Header>
<telerik:GridViewDataColumn.CellTemplate>
<DataTemplate>
<ItemsControl ItemsSource="{Binding DesignStatusViewModels}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel
Orientation="Horizontal"
HorizontalAlignment="Right"
TextElement.FontSize="12"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<ContentPresenter
Grid.Row="0"
Content="{Binding }"
VerticalAlignment="Center"
ContentTemplateSelector="{StaticResource DesignStatusContentTemplateSelector}"
Margin="2,0,2,0"/>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</DataTemplate>
</telerik:GridViewDataColumn.CellTemplate>
</telerik:GridViewDataColumn>

Each IMvvmViewModel has a bool, and a template, the template is responsible for showing the activated or not activated icon for each case, for example:

[DesignStatusTemplates(Template = typeof(DesignStatusRushOrderTemplate))]
publicpartialclassDesignStatusRushOrderViewModel : IMvvmViewModel
{
publicbool IsRush { get; set;}
}

[DesignStatusTemplates(Template = typeof(DesignStatusExternalOrderTemplate))]
publicpartialclassDesignStatusExternalOrderViewModel : IMvvmViewModel
{
publicbool IsExternal { get; set;}
}

What I need is to make a custom filter for this column, which can filter with a checkbox or whatever is easier, for example all orders that have DesignStatusRushOrderViewModel -> IsRush == true.

Thank you very much! Juan

Changing font size RadNavigationView menu items

The RadNavigationView menu items don't seem to respect font size palatte settings. That is,

        FluentPalette.Palette.FontSize = FontSize;
        FluentPalette.Palette.FontSizeS = FontSizeSmall;
        FluentPalette.Palette.FontSizeL = FontSizeLarge;

will change the font sizes in grids, buttons, regular menus, etc., but not navigation menu items. How can we get this working? XAML code:

    <Window.Resources>
        <telerik:StringToGlyphConverter x:Key="StringToGlyphConverter" />
            <Style TargetType="telerik:RadNavigationViewItem">
                <Setter Property="Content" Value="{Binding Title}" />
                <Setter Property="ItemsSource" Value="{Binding SubItems}"/>
                <Setter Property="Icon" Value="{Binding IconGlyph}" />
                <Setter Property="IconTemplate">
                    <Setter.Value>
                        <DataTemplate>
                            <telerik:RadGlyph Glyph="{Binding Converter={StaticResource StringToGlyphConverter}}" Font="fas" />
                        </DataTemplate>
                    </Setter.Value>
                </Setter>
            </Style>
    </Window.Resources>

        <telerik:RadNavigationView Grid.Row="1"
            x:Name="NavigationView" ItemsSource="{Binding MenuItems}"
                                   AutoChangeDisplayMode="False"
                                   DisplayMode="Expanded"
                                   AllowMultipleExpandedItems="True"
                                   SubItemsIndentation="15"
                                   telerik:AnimationManager.IsAnimationEnabled="True"
                                   SelectionChanged="OnNavigationViewSelectionChanged">
            <telerik:RadNavigationView.Content>
                <Frame

                                Content="{Binding ContentPage}"/>
            </telerik:RadNavigationView.Content>
            <telerik:RadNavigationView.PaneFooter>
                <telerik:RadNavigationViewItem Content="Settings" 
                                               Command="{Binding NavigateItemSelectedCommand}"
                                               CommandParameter="Settings"
                                               IconTemplate="{x:Null}">

Getting cell and item when cell is clicked

Say I have a RadGridView bound to this class:

    public class UserActivityNoteDTO
    {
        public Guid ActivityNoteId { get; set; }
        public string ActivityType { get; set; }
        public string ActivityStage { get; set; }
        public string EntityId { get; set; }
        public string MemberId { get; set; }

}

When a cell is clicked I need to get the ActivityNoteId and what was clicked and the value. So if I click a member id, I need to get the ActivityNoteId and MemberId and know MemberId was clicked (and not EntityId).

I've seen examples where you can get the rowitem or cell value but not both.
