Release 2025.2.520 (2025 Q2)

Visual Studio 2022 crashes when working with a solution containing two WinForms projects:

  • Project 1: WinForms (.NET 9) with Telerik
  • Project 2: WinForms (.NET 6) without Telerik

Steps to Reproduce:

  1. Create a new solution in Visual Studio 2022.
  2. Add two WinForms projects:
    • Project 1: WinForms (.NET 9) with Telerik
    • Project 2: WinForms (.NET 6) without Telerik
  3. Open the WinForms designer for a form in Project 1 (Telerik, .NET 9).
  4. Without closing the designer, open the WinForms designer for a form in Project 2 (.NET 6, no Telerik).
  5. Switch to the code view of the form in Project 2.
  6. Switch back to the WinForms designer in Project 2.

Expected Result:
Visual Studio should smoothly switch between code and designer views without issues.

Actual Result:
Visual Studio freezes and crashes after switching back to the WinForms designer in Project 2.

Environment:

  • Visual Studio 2022
  • Windows Version: (Windows 11 x64)
  • Telerik WinForms Version: (2025.1.211)

Additional Notes:

  • The issue seems to be related to handling different .NET versions and Telerik components in the same solution.
  • The crash occurs consistently when following the steps above.
  • No explicit error messages are shown before Visual Studio closes.

When I show some text and set IsWordWrapEnabled to true... the horizontalscrollbar disappears


but when I set IsWordWrapEnabled to false after this, the horizontalscrollbar does not appear 

in your code I saw this:

                ScrollBarVisibility newScrollVisibility = editor.IsWordWrapEnabled ? ScrollBarVisibility.Disabled : ScrollBarVisibility.Auto;
                editor.SetValue(HorizontalScrollBarVisibilityProperty, newScrollVisibility);

But this .Auto property doesn't seem te work. 
Further more, next to this problem, I'd like to set this horizontalscrollbar to appear and disappear depending on the text width...
but I'm afraid this would be depending on the .auto property

Since 2025 Q2 you'll get this error message when you try to open a flyout on a control that is not a Form. This does not happen with 2025 Q1.

Might be related: https://feedback.telerik.com/winforms/1688619-radform-clientsize-on-inherited-radform-is-broken

However, this time I have no patch / workaround. I have not the time to investigage deeper at the moment, so update to Q2 not possible for me at the moment.

In this particular case, the main monitor on which the Form is shown is 225. While the application is running, the DPI is changed to 100%. The controls size is scaled correctly, however, the Font inside the controls is not.

It will be nice if one can add his custom sub menu items at design-time through the 'Add new item' menu. This was supported in the past, but the support was removed together with the introduced design-time optimizations.

CAB Enabling Kit - there is no way to show again smartpart that is already closed into RadDockWorkSpace.

Workaround:

         protected override void OnDockWindowClosing(DockWindowCancelEventArgs e)
        {
            if (!notifications[Suspend_Close] && e.NewWindow.Controls.Count > 0)
            {
                this.composer.SetActiveSmartPart(null);
                WorkspaceCancelEventArgs args = new WorkspaceCancelEventArgs(e.NewWindow.Controls[0]);
                OnSmartPartClosing(args);
                e.Cancel = args.Cancel;
                e.NewWindow.CloseAction = DockWindowCloseAction.Hide;
            }
            base.OnDockWindowClosing(e);
        }

        protected virtual void OnActivate(Control smartPart)
        {
            notifications[Suspend_Activated] = true;
            DockWindow dockWindow = GetSmartPart(smartPart);
            if (dockWindow != null && this.ActiveWindow != dockWindow)
            {
                dockWindow.Show();
                this.ActivateWindow(dockWindow);
            }

            notifications[Suspend_Activated] = false;
        }

When the Visual Style Builder is opened from the Smart Tag menu, VS loses focus. If you open it and close it after that you will see that the focus is not in the Visual Studio anymore.

Steps to reproduce:
1. Paste image in the editor
2. Press enter (the image is pasted again everytime Enter is pressed)

This is not issue in the control. It is cased by the test application. The focus remains on the paste button and for this reason the image is pasted when enter is pressed.

Use the attached application and open its form at design time. Try to change something and to save the changes. Exception will occur.
