Drag and DropText outside of RichTextBox

I would like to drag text outside of a WPF RadRichTextBox into a different App.

It seems that dragging any text just outside of this control is not possible, not even within the same app.
IMHO the problem is, that text can be moved within this control, and this feature cannot be deactivated.

Thanks a lot in advance for any hints.

Edit: Just checked with standard RichTextBox (FlowControl) no problems out of the box. I can drag text internal and as soon as mousepointer went outside, everything is fine and works there. Try this with RadRichTextBox and the Prompt goes crazy inside of your control.

Is it possible to get the mouse coordinates while in a handler for this event? It seems like Mouse.GetPosition isn't returning valid information.

But this version is not available throught nuget.telerik.

How can I use it in my CI/CD?

[Solved] Change Visibility of RadBadge

Hello,

i'm using a RadButton with a RadBadge to open an dialog with new messages.

Now i'm wondering how to hide the RadBadge when there are no new messages...

In my viewmodel i have a property (bool) that indicates, if the badge should be visible or not...

Here's the XAML - its part of a datatemplate for a RadWindow:

<telerik:RadButton x:Name="manButton"  Grid.Column="7" Margin="10,6" Command="{Binding ShowManCommand}" Focusable="False">
    <telerik:RadButton.Content>
        <Image Source="{iconPacks:MaterialImage CommentTextMultipleOutline, Brush=White}" Margin="4" />
    </telerik:RadButton.Content>
    <telerik:RadBadge.Badge>
        <telerik:RadBadge BadgeType="ContentOnly"  AnchorPosition="1,1" Position="1.1,0.4" 
                          Geometry="{telerik:Geometry Type=Oval}" Background="Red" 
                          FontSize="12" Height="16" Width="28"
                          Content="{Binding ManMessageCount}" 
                          Visibility="{Binding IsManBadgeVisible, Converter={converter:BoolToVisibilityConverter}}"/>
    </telerik:RadBadge.Badge>
</telerik:RadButton>

Is there a possibility to hide/collapse the RadBadge? It seems that the visibility property isn't working...

ComboBox with GridView? (oh, and a rant :)

I've been working with the Telerik WPF controls for the last couple of months and appreciating them.

<rant>

However, I have a major gripe as well: most of the examples are FAR too complex. Here's a perfect example. I'm trying to get a ComboBox to work with a GridView. There is an example that does pretty much exactly what I want at https://github.com/telerik/xaml-sdk/tree/master/ComboBox/DropDownWithHeaders. However,

A simple clone from the repository won't run. That seems fundamental to me. When I look into it, the problem is themes. A simple example should not even include themes! I would suggest a proper example would allow me to clone and run, with nothing else on my machine but Visual Studio.
When I look into the actual example, it is anything but simple! The control template is 155 lines of code!?!?! How do I sort through that quickly and figure out what I need and don't need? I don't need all kinds of animation or fancy styles. For the purposes of learning the controls, I need the absolute minimum to make it work!

There is also an example of this at https://www.telerik.com/forums/radcombobox-with-radgridview, but it suffers from the same problems.

This kind of thing seriously makes me ponder going back to our old controls provider.

</rant>

Now, can someone please provide me with a simple example of a ComboBox that uses a GridView for the drop-down?

Of course perhaps I'm using the wrong control. Maybe I should be using the MultiColumnComboBox, but the end results shown in the examples make it look nothing like a traditional ComboBox. (Again, that may be owing to a lack of a good, simple example.)

Help?

RadDiagram panning

I am using the RadDiagram component inside a WPF application for a sketching software. The default behavior of the RadDiagram is to enable movement of the diagram with the Ctrl + Left click and drag shortcut. I want to enable the program to also work with Middle mouse button click and drag. Currently, I am using custom RadDiagram tools, which derive from their base classes. For example, MyPanningTool:

using System;
using System.Windows.Input;
using XXX.Core.Models.EventArgs;
using Telerik.Windows.Diagrams.Core;

namespace XXX.XXX.Presentation.Tools
{
    internal class MyPanningTool : PanningTool
    {
        private const string PanningToolName = "Panning Tool";
        private SelectionMode _selectionMode;
        private ToolService _toolService;

        public MyPanningTool()
        {
            Cursor = DiagramCursors.Dragging;
        }

        private void ActivatePanningTool()
        {
            _toolService ??= Graph.ServiceLocator.GetService<IToolService>() as ToolService;
            _toolService?.ActivateTool(PanningToolName);
        }

        private void ActivatePointerTool()
        {
            _toolService ??= Graph.ServiceLocator.GetService<IToolService>() as ToolService;
            _toolService?.ActivateTool("Pointer Tool");
        }

        public override bool KeyDown(KeyArgs key)
        {
            if (!IsActive) return false;
            base.KeyDown(key);

            if (key.Key != Key.Enter && key.Key != Key.Escape && !ToolService.IsControlDown)
            {
                ActivatePanningTool();
                return false;
            }

            return false;
        }

        /// <inheritdoc />
        public override bool MouseDown(PointerArgs e)
        {
            if (IsActive)
            {
                _selectionMode = Graph.SelectionMode;
                Graph.SelectionMode = SelectionMode.None;
            }

            if (ToolService.IsControlDown || Mouse.MiddleButton == MouseButtonState.Pressed)
            {
                //ActivateTool();
                //ActivatePanningTool();
                return base.MouseDown(e);
            }
                
            return IsActive && base.MouseDown(e);
        }

        /// <inheritdoc />
        public override bool MouseMove(PointerArgs e)
        {
            if (ToolService.IsControlDown || Mouse.MiddleButton == MouseButtonState.Pressed)
            {
                return base.MouseMove(e);
            }
            return IsActive && base.MouseMove(e);
        }

        /// <inheritdoc />
        public override bool MouseUp(PointerArgs e)
        {
            if (!IsActive) return false;

            Graph.SelectionMode = _selectionMode;

            try
            {
                base.MouseUp(e);
            }
            catch
            {
                // ignored
            }



            if (ToolService.IsControlDown || Mouse.MiddleButton == MouseButtonState.Pressed) return base.MouseUp(e);

            ActivatePointerTool();
            ToolChangedEvent?.Invoke(null, new ToolChangedEventArgs("Pointer Tool"));
            return true;
        }

        public static event EventHandler<ToolChangedEventArgs> ToolChangedEvent;
    }
}

I've tried to capture the Middle mouse click event on the RadDiagram and transfer them to the Panning tool Mouse click and and Move events, but this doesn't seem to do the trick.

How can I pass KeyTriggers from a RadPane to the ToolWindow when created?

I am working on an application that uses a DockingPanesFactory to add RadPanes to a window. These RadPanes have KeyTriggers that do not execute when floating. I understand that it is because it becomes a ToolWindow and therefore it is not in the same visual tree. How can I make sure tgatvmy key triggers get passed to the ToolWindow so the commands execute?

Set focus to first cell of selected item when RadGridView initially shown

What is necessary to get a RadGridView to focus the first cell of the row that is selected, when the SelectedItem is bound, when the grid is first shown? You can see in the screenshot that the first cell of the first row is focused even though the third row is selected via binding. You can also see the properties that are set for the grid below.

As soon as a user clicks on another row in the grid, the outlining / focus on the first cell goes away and moves to the first cell of the row the user selected.

                    <telerik:RadGridView
                        x:Name="fieldsGrid"
                        HorizontalAlignment="Stretch"
                        VerticalAlignment="Stretch"
                        IsReadOnly="True"
                        AutoGenerateColumns="False"
                        SelectionMode="Single"
                        SelectionUnit="FullRow"
