I have a RadGridView where i've replaced the "Full Text Search" with a custom control (TextBox + Label) 

I'm using a Debouncer to collect text changes from the Textbox and then after 300msec - do the search:


if (e.PropertyName == "Query")
{
	debounce.Debounce(() =>
	{
		Dispatcher.Invoke(() =>
		{
			FilterByQuery();
		});
	});
}
FilterByQuery() : 
var searchBytextCommand = RadGridViewCommands.SearchByText as RoutedUICommand;
searchBytextCommand.Execute(Query, radgrid);

Query = String property

radgrid = x:name of the RadGridView.

at some random point in time of the lifetime of the WPF program, this function stops working !

- I dont have any other case of the Debouncer stops working so i trust that it's not the issue. 

- WPF Databinding and PropertyChanged events are also working 1000 other places in the program without failing, so i trust that they work too.

- This leads me to believe that the RadGridViewCommands might have an issue..

Hi, I would like to change style of schedulerdialogs in ScheduleView. For example, when I click on delete appointment button, this is the style I see:

But I want the style to look like this:

As you can see, the header of this dialog looks different. I am only able to achieve this look for Radwindow not for SchedulerDialog. Is there a way ro do it?

Thank you for your answer

We have a issue with WPF RadComboBox to disable the auto selection of first item while databinding.

I have large set of data (say 10000 items) in the application cache.

<telerik:RadComboBox
                                        x:Name="itemBox"
                                        HorizontalAlignment="Stretch"
                                        telerik:TextSearch.TextPath="Name"
                                        CanAutocompleteSelectItems="False"
                                        DisplayMemberPath="Name"
                                        EmptyText="Select item"
                                        IsEditable="True"
                                        IsFilteringEnabled="True"
                                        IsReadOnly="False"
                                        IsTextSearchEnabled="True"
                                        ItemsSource="{Binding ItemCollection, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
                                        OpenDropDownOnFocus="True"
                                        ScrollViewer.VerticalScrollBarVisibility="Auto"
                                        SelectedItem="{Binding SelectedItem, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
                                        TextSearchMode="Contains">

                                                <telerik:EventBinding
                                                Command="{Binding BeginSearchCommand}"
                                                EventName="KeyUp"
                                                PassEventArgsToCommand="True" />
</telerik:RadComboBox>

We have the RadCombobox with Filter enabled.

BeginSearchCommand relay command method has implementation of filtering the cached ItemCollection and setting the value.


this.ItemCollection = new QueryableCollectionView(new ObservableCollection<ItemModel>(filtereditems));

I first load 50 items in RadCombobox and the user will try to search the items from SearchText . Then the items in the cache is filtered with searchtext and the result is assigned with the datasource property.

  1. User start searching
  2. The first item from the filtered result occupies the search text.

The couple of action above continues. Please help us disable autoselect  while databinding.

Hello
I have a radgridview with two columns (for simplicity)
The first is defined like this:

RiassuntoSorgentiGrid.Columns.Add(new GridViewDataColumn()
{
				Header = Utility.LoadString(ResourcesKeys.RipetizioniSorgente),
				ColumnGroupName = GENERALGROUPNAME,
				DataFormatString = "D",
				DataMemberBinding = new Binding("Sorgente.Ripetizioni")
				{
					Mode = BindingMode.OneWay
				}
});


The second like this:

RiassuntoSorgentiGrid.Columns.Add(new GridViewDataColumn()
{
				Header = Utility.LoadString(ResourcesKeys.RipetizioniSorgente),
				ColumnGroupName = GENERALGROUPNAME,
				DataFormatString = "D",
				DataMemberBinding = new Binding($"Sorgente.LivelliSingoli[{parametro.Id}][{l}]")
				{
					Mode = BindingMode.OneWay
				}
});


where parametro.Id and l are variables correctly defined and not null.
The grid works good, but in the second columns filtering and sorting are not active, while in the first they do.

Is there a reason for this behavior?
Thank you
Luigi

https://www.telerik.com/forums/setting-background-color-when-control-is-readonly

The above link shows where someone had a similar issue but isn't clear on how to solve it.

I want to set a text box to not look disabled when it is readonly.
In the example below I set the background to red just to demonstrate that nothing happens.

I think it not happening because the application is using a theme (windows11)

Can I set the BasedOn to something that means "current theme", so that it will work?

<!-- Want readonly to not look disabled in many places -->

<Style x:Key="LxReadOnlyRadW"
       TargetType="telerik:RadWatermarkTextBox"
       BasedOn="{StaticResource {x:Type telerik:RadWatermarkTextBox}}">
    <Style.Triggers>
        <Trigger Property="IsReadOnly"
                 Value="True">
            <Setter Property="Background"
                    Value="red" />
        </Trigger>
    </Style.Triggers>
    <Setter Property="IsReadOnly"
            Value="True" />
    
</Style>

I would like use a RadVirtualKeyboard to enter pin code in my application. And when I use it with DefaultKeyboardLayout.Numpad it work as expected - shows small pop-up windows with numpad keyboard. But when I try to load my custom layout it shows the same small window but width of keyboard's buttons is super wide. 

I seems that loading custom layout reset width of UI element to full size keyboard and all my customs buttons are stretched.

Could you help me?

var kb = new RadVirtualKeyboard() { VirtualKeyboardTemplateSelector = (VirtualKeyboardTemplateSelector)(MyView.FindResource("KeyTemplateSelector")), DefaultKeyboardLayout = DefaultKeyboardLayout.Numpad }; keyboardWindow = new RadVirtualKeyboardWindow(kb) { Header = "Enter you number", ResizeMode = ResizeMode.NoResize, CanClose = false, Width = 260 };

//load custom layout

byte[] byteArray = Encoding.UTF8.GetBytes(keyLayout); Stream stream = new MemoryStream(byteArray); kb.LoadLayout(stream); keyboardWindow.Show();

Here is my layout:

<RadVirtualKeyboard xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 
    <Grid> 
        <Grid.RowDefinitions> 
            <RowDefinition Height="*" /> 
        </Grid.RowDefinitions> 
        <Grid.ColumnDefinitions> 
            <ColumnDefinition Width="*" /> 
        </Grid.ColumnDefinitions> 
        <KeysLayout KeySpacing="0.1" Grid.Row="0" Grid.Column="0"> 
            <Rows> 
                <Row> 
                    <Keys> 
                        <Key KeyType="Numpad" Width="1" Height="1" VirtualKey="103" /> 
                        <Key KeyType="Numpad" Width="1" Height="1" VirtualKey="104" /> 
                        <Key KeyType="Numpad" Width="1" Height="1" VirtualKey="105" /> 
                        <Key KeyType="Normal" Width="1" Height="1" VirtualKey="109" /> 
                    </Keys> 
                </Row> 
                <Row> 
                    <Keys> 
                        <Key KeyType="Numpad" Width="1" Height="1" VirtualKey="100" />

                        <Key KeyType="Numpad" Width="1" Height="1" VirtualKey="102" /> 
                        <Key KeyType="Normal" Width="1" Height="1" VirtualKey="107" /> 
                    </Keys> 
                </Row> 
                <Row> 
                    <Keys> 
                        <Key KeyType="Numpad" Width="1" Height="1" VirtualKey="97" /> 
                        <Key KeyType="Numpad" Width="1" Height="1" VirtualKey="98" /> 
                        <Key KeyType="Numpad" Width="1" Height="1" VirtualKey="99" /> 
                        <Key DisplayText="Enter" KeyType="Special" Width="1" Height="1" VirtualKey="13" /> 
                    </Keys>

            </Rows> 
        </KeysLayout> 
    </Grid> 
</RadVirtualKeyboard> 

And how it is showed

Hi,

i would like to change the Field Displayname of Properties used in the Pivot-Fieldlist.

I tryed to use the AddingContainerNode Event from LocalDataSourceFieldDescriptionsProvider, but it's only possible to change the

display name like

    (e.ContainerInfo as PropertyInfoFieldInfo).DisplayName = "Test"

This works for the aggregate list, but in List of fields there is always the name of property visible.

I tryed to change also the caption of ContainerNode but there is no Setter implemented.

    e.ContainerNode.Caption ="Test";  //it's not possible, but ist seems to be there right way 

Is there another way to Change the Caption.

Thanks for help.

Best regards

Stephan

Please help. I'm trying to get keyboard inputs to work for a RadMenu. Here are the three different ways I'm trying to get working. Just to be clear, NONE work. And yes, there are valid commands backing these. When I try this with Window.InputBindings I can get it to work, but i would like to have the keyboard declaration as near the menu as possible. This shouldn't be this hard, please help.

<telerik:RadMenu Grid.Row="0" NotifyOnHeaderClick="True" VerticalAlignment="Center" Grid.ColumnSpan="3">
			<telerik:RadMenuItem Header="_File">
				<telerik:RadMenuItem Header="_New" InputGestureText="Ctrl+N" Command="{Binding NewCommand}">
					<telerik:RadMenuItem.InputBindings>
						<KeyBinding Gesture="Ctrl+N" Command="{Binding NewCommand}"/>
					</telerik:RadMenuItem.InputBindings>
				</telerik:RadMenuItem>
				<telerik:RadMenuItem Header="_Save" InputGestureText="Ctrl+S" CommandTarget="{Binding SaveCommand, Mode=OneWay}" />
				<telerik:RadMenuItem Header="_Cancel" InputGestureText="ESC"/>
				<telerik:RadMenuItem Header="_Delete" InputGestureText="Ctrl+D" Command="{Binding DeleteCommand}" />
				<telerik:RadMenuSeparatorItem />
				<telerik:RadMenuItem Header="E_xit" InputGestureText="Alt+F4" Command="{Binding FileExitCommand}" />
			</telerik:RadMenuItem>
			<telerik:RadMenuItem Header="_Help">
				<telerik:RadMenuItem Header="_Support" Command="{Binding NavigateToAvantiSupportWebpageCommand}" CommandParameter="https://avantisystems.com/support-portal/"/>
				<telerik:RadMenuSeparatorItem />
				<telerik:RadMenuItem Header="_About" Command="{Binding HelpAboutCommand}"/>
			</telerik:RadMenuItem>
		</telerik:RadMenu>

Hello,

we found that in version R1 2024 of Telerik UI for WPF the opened dockable floating windows are set by default to be topmost also over other application windows.

This behaviour is easily reproducible in the demo application.  It is enough to set solution explorer as a floating dockable window in the First Look example of the Docking and open e.g. internet explorer over the Telerik demo application. In version R3 2023, the solution explorer window was not visible anymore, in R1 2024 is the window still visible.

Is it some new feature or bug?

Thank you.

Best regards,

Jakub
