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"

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

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.

Hierarchical RadGridView Delete just Child

Hi,

I have the attached hierarchical RadGridView.

In this I want to implement, that users can delete a single child and also that they can delete a parent.
Now in the way I thought it would work, if you press the Delte Key on the Keyboard, it triggers both events.

Is there a way to prevent this from happening?
And if not, how would I check if the event was triggered by a the child RadGridView or the parent?

Greetings,

Benedikt

Tables and Images - Always fill width of RTB

I'd like to know if I can make it so tables and images always fill width of RichTextBox.

I have a RichTextBox control that is not very wide and I want text to wrap and not give them a horizontal scrollbar. I can't set an explicit width as this needs to be dynamic. Is there anyway that I can make it so that tables/ pictures are inline and always occupy the entire width?
