To reproduce:

- .NET Core version: 3.1

- Visual Studio 2022: Version 17.0.0 Preview 7.0

 - Telerik UI for WinForms version: 2021.3.1019-hotfix

1. Create a new Excel-Inspared template project.

2. Select the Review tab and the Properties section try to open the Items collection.

The attached Error.gif illustrates the steps.

Workaround: use the Smart tag (see SmartTag.gif)

The snap layouts window can be opened by using the Win+Z keyboard combination, but when the mouse is over the Maximize button of RadForm, the window is not shown.
MSDN information is available here: https://docs.microsoft.com/en-us/windows/apps/desktop/modernize/apply-snap-layout-menu

Following the guides from MSDN, we need to override the WndProc method of the form, listen to the WM_NCHITTEST message, and return HTMAXBUTTON result when the mouse is over the maximize button.

private const int HTMAXBUTTON = 9;
protected override void WndProc(ref Message m)
{
    if (m.Msg == NativeMethods.WM_NCHITTEST)
    {
        // Get the hit test location from message parameters
        Point location = this.ParseIntPtr(m.LParam);
        location = this.GetMappedWindowPoint(location);

        // Get the hit tested element and check if it is the Maximize button
        RadElement element = this.ElementTree.GetElementAtPoint(location);
        if (element == this.FormElement.TitleBar.MaximizeButton)
        {
            m.Result = new IntPtr(HTMAXBUTTON);
            return;
        }
    }

    base.WndProc(ref m);
}

private Point ParseIntPtr(IntPtr param)
{
    if (IntPtr.Size == 4) //x86
    {
        return new Point(param.ToInt32());
    }
    else //x64
    {
        long intParam = param.ToInt64();
        short x = (short)intParam;
        short y = (short)(intParam >> 16);
        return new Point(x, y);
    }
}

protected virtual Point GetMappedWindowPoint(Point screenPoint)
{
    NativeMethods.POINT inputPoint = new NativeMethods.POINT();
    inputPoint.x = screenPoint.X;
    inputPoint.y = screenPoint.Y;

    if (this.IsHandleCreated)
    {
        NativeMethods.MapWindowPoints(new HandleRef(this, IntPtr.Zero), new HandleRef(this, this.Handle), inputPoint, 1);
    }

    return new Point(
    inputPoint.x + this.FormBehavior.ClientMargin.Left,
    inputPoint.y + this.FormBehavior.ClientMargin.Top);
}

1. Run Telerik Theme Viewer app

2. Set Office2019Dark theme

3. Navigate to "Item Containers" tab

You will see that radTreeView does not display nodes.

Workaround:

this.radTreeView1.FullRowSelect = false;

1. Set ThemeResolutionService.AllowAnimations = false;

2. Run the attached project and set a filter via the GridFilterButton popup

3. Click "Clear filter" option in the GridFilterButton popup

You will see that the GirdFilterButton visual indication is of an applied filter. However, there is no applied filter.

1. Run TelerikExamplesLauncher.exe - GanttView "First Look" example
2. Scroll and select a task near the bottom, for example: "Send your engagement announcement to newspapers" under "The Guest > 6 Months +"
3. Use splitter to resize between TextView and GraphicalView

You will see that GraphicalView doesn't move but TextView loses task position and scrolls to the top.

Note that using mouse Scroll refreshes the correct position of TextView on the selected task.

When we have start position set to center screen:

            this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;

RadForm does not calculate the correct location of the form on HDPI devices.

1. Create a Winforms application containing RichTextEditorRibbonBar

2. Add a CodedUI test project

3. Start the application and add a new CodedUITest

4. Drag the Spy from the "UIMap - Coded UI Test Builder" onto a disabled radButtonElement - for example "Delete All" button in the "Review" tab

You will see that the Enabled property value is true instead of false.

I have installed the suite of controls for winforms, but I can't get them to appear in the toolbox. When I use Extension / Telerik / Telerik UI for Winforms / Launch Toolbar configurator it shows me the control options and is supposed to add them to the Toolbox, but they don't appear. If I select the Show All option then all the Telerik control categories appear, but none are enabled. So I did it manually and it remains the same.

This image shows the toolbox after using the Telerik extension Launch toolbox configurator

As you can see, no tab appears with the Telerik controls.

And if I tell it to show me all the tabs, the Telerik controls do appear, but they are not enabled, as can be seen in the following image:

Thanks,

Juan Carlos

Follow the steps:

1. Please enter "0.12345"

2. Using the left arrow navigate after "1" and hit Backspace to delete "1"

3. Enter "6". It would be inserted in the wrong position

Hello support,

i use the radBrowseEditor.

Here the code:

        private readonly string ActualPath_LiteDB = "";

        public F_ApplicationsSettings()
        {
            InitializeComponent();

            //set up actual paths
            ActualPath_LiteDB = Settings.PathToLogLiteDB;
            radBrowseEditor_db_path.Value = ActualPath_LiteDB;

            this.Text = F_Translations.GetTranslationText("settings");
        }

When i set the DialogType to FolderBrowseDialog the initial directory the its working:

But if i set it the DialogType to RadOpenFolderDialog its not working. Its always showing the Desktop folder:
