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.

 Licensing watermark shows on RadForm in the Excel/Word Add-in projects.

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.

Themes are applied partially to RadSpellChecker's forms.

Exception is thrown, when best fit columns is performed over a column with equal MaxWidth and MinWidth property values.

FIX.Radbutton -throws exception In design time when add image in ICO format c

Application button is overlapping the first tab when the theme is "Office2007Black".

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.

Implement VSB Wireframes, design, UX

The VSX toolbox configurator fails to open after installing RadControls for WinForms Q3 2010.

As a <role> I want <ability> so that <benefit>.

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.

1. Create a project with RadTextBox
2. Compile the project.
3. Highlight an existing multiline RadTextBox
4. Double Click multiline property (sets to false and control reduces to 1 line correctly)
5. Double Click multiline property again (control correctly returned to previous multiline size)
6. Compile - Fails with above error

1. Create a new project with RadChartView.
2. Add some data in the chart.
3. Add the following code:
new Telerik.WinControls.Themes.DesertTheme();
ThemeResolutionService.ApplicationThemeName = "Desert";
4. Run the project.

One should be able to persist to a file all changes made when using the element hierarchy editor at design time.

- the initial object property value is not displayed
- the color change is not always reflected, even though the object implements INotifyPropertyChanged

Adding the binding in code works correctly.

1. Bind the grid to something with more than one level hierarchy
2. Remove some child column in property builder
3. Close and open VS2008
4. In the property builder the same column that was removed, appears with the check box checked (and it shouldn't be). But when the application starts the column does not appear in the grid(which is right).
5. Open property builder again, and remove another column
6. Start the application again, the column that we have just removed is gone, as it should, but the first column appears.

Same scenario appears when using the designer.
