Steps to Reproduce:

  1. Create a new WinForms application targeting .NET 9.

  2. Add a RadStatusStrip to the main form.

  3. Run the application.

  4. Snap the form to the left or right edge of the screen (using Windows Snap).

  5. Minimize the form.

  6. Restore the form.

Expected Behavior:
The form should maintain its original size and remain fully visible on screen after being restored.

Actual Behavior:
Every time the form is minimized and restored, it increases in height. After a few cycles, the bottom part of the form — including the RadStatusStrip — becomes hidden behind the Windows taskbar (Start menu).

Additional Info:

  • The issue only occurs when a RadStatusStrip is added to the form.

  • The issue does not occur when using a standard StatusStrip from WinForms.

  • The problem occurs consistently and can be reproduced easily.

  • Tested both in debug mode and with a compiled executable.

Attachments:

  • Screenshots (before and after restore).

  • Sample reproduction project (if needed).

    This is only repeated in windows 10

 This issue starts happening as of Q2 (2025.2.520) version.

Workaround: override SetClientSizeCore() inside of inherited RadForm

public partial class RadForm2 : RadForm1
{
    protected override void SetClientSizeCore(int x, int y)
    {
        base.SetClientSizeCore(x, y);

        if ((!this.IsLoaded || !this.IsHandleCreated) &&
            this.IsInitialized)
        {
            MethodInfo mi = typeof(Form).GetMethod("SetClientSizeCore", BindingFlags.NonPublic | BindingFlags.Instance);
            if (mi != null)
            {
                IntPtr ptr = mi.MethodHandle.GetFunctionPointer();
                Action<int, int> baseSetClientSizeCore = (Action<int, int>)Activator.CreateInstance(
                    typeof(Action<int, int>), this, ptr);

                baseSetClientSizeCore.Invoke(x, y);
            }
        }
    }
}

When enabling AutoSize on all RadTextBoxControl elements on a Form and the Form has its AutoSize porperty set to True, then the size of the TextBoxElement inside the TextBox autosizes wrong. See the pictures. This happens at runtime and under specific conditions also at design time.

If you change Form.AutoSize to False OR at least ONE RadTextBoxControl to AutoSize = False then everything works as normal. But if ALL RadTextBoxControl has AutoSize to True and The Form.AutoSize is True, then this happens.

In this scenario, we have custom RadListFilterPopup. There could be a scenario in which we don't need the default menu items( input textbox, list of distinct values, buttons). If we override the CreateListFilterMenuItems() method and don't call the base code, NullReferenceException will be thrown in the Dispose() method.

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.

The control allows you to scroll the view while dragging and appointment. In a case when the appointment is at the bottom of the view and we try to move it above, the view will scroll to see the top cells. When the mouse is above the column header cells, the scroll stops. This could be improved.
