The Anchor and Dock property is not relevant to the RadPopupContainer and should not be taken into account while calculating the size of the popup drop-down.

Workaround:

Avoid setting the Anchor and Dock properties of the RadPopupContainer.

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.

Hello,

We encountered problems with configuration of the toolbox in Visual Studio 2022 when out-of-proc designer is active.
More information about the usage and reason for the out-of-proc designer: https://github.com/dotnet/winforms/blob/main/docs/designer/designer-selection.md

Tested environment:
- Visual Studio 2022
- .NET Framework 4.7.1
- 32-bit application
- Windows 11 Pro
- Telerik UI For Winforms 2025.2.520.462

When trying to add a rad control from the toolbox the error in attachment occurs.

Workaround:
- Disable the out-of-proc designer in the project file:

<UseWinFormsOutOfProcDesigner>False</UseWinFormsOutOfProcDesigner>

Clicking the filter icon will reopen the filter popup. In the following scenario, the filter pop-up is open. If we click the filter icon while the filter popup is open, it will close it and reopen it. This leaves the end user with flashing behavior. The filter icon should close the filter popup if it is open.

In the Visual Theme Builder (fresh installed Telerik UI for WinForms) you'll get an error because the directory "VbsRecoveryData" seems to be missing. Creating the directory before "package.Compress(path)" fixes this for me.

Memory increases when rearranging Dock windows at runtime. In this case, we have several DocumentWindows. If we change the dock position of each window at runtime, memory consumption rises. By default, the TabStripItem for each window is created on the fly due to the rearranging mechanism. However, these instances are kept alive, thus increasing memory usage.

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.

 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);
            }
        }
    }
}

This happens when popup is opened for the first time. When I close the popup and reopen it again, the popup is now correctly trimmed to fit the 12 items.
