Run the app then drag the left side of the window to the right as far as possible, then rapidly drag the left side of the window back and forth. At some point, the application should crash with the exception (the project is available for download internally only)

- Add RadRibbonForm
- Set the radRibbonBar1 RightToLeft property to YES at design time
- Close the designer and open it again -> another ribbon is showing up

Workaround: done set the ribbon's RightToLeft property, just set the RightToLeft property of the form itself.

Accelerator Key is working but not underlined (underline is enabled in windows 10 and visible in other applications).

Telerik.WinControls.UI, Version=2019.1.117.40

I used RadPageView under the theme "VisualStudio2012LightTheme" .

The ViewMode of RadPageview is Stack.

I wanted to change the font size of page header in runtime but it was not workable.

If I changed the theme to VisualStudio2012DarkTheme or Office2013LightTheme, it worked fine.

 Hi. I try to resolve the problem as u describe but Still having the same error msg Any other solution

RE: Bug Report ID:1385123 -- when upgrading from r3 sp1 2018 to r1 2019 using vb.net 2012 i received an error

auto complete feature not working. i'm using unbound mode

my operating system win 10 64 bit. visual studio 2015. .net 4.6.1 installed. convert to telerik controls menu not showing

How to reproduce: set the ShowIcon property to false.

this.ShowIcon = false;

Use attached to reproduce.

Workaround:

public RadForm1()
{
    InitializeComponent();
    radPdfViewer1.ContainerElement.BookmarksTree.SelectedNodeChanged += BookmarksTree_SelectedNodeChanged;
}

private void BookmarksTree_SelectedNodeChanged(object sender, Telerik.WinControls.UI.RadTreeViewEventArgs e)
{
    Telerik.Windows.Documents.Fixed.Model.Navigation.BookmarkItem bookmark = e.Node.Tag as Telerik.Windows.Documents.Fixed.Model.Navigation.BookmarkItem;

    if (bookmark != null && bookmark.Destination == null)
    {
        GoToAction goToAction = bookmark.Action as GoToAction;
        if (goToAction != null && goToAction.Destination != null)
        {
            radPdfViewer1.PdfViewerElement.GoToDestination(goToAction.Destination);
        }
    }
}

The issue can be reproduced in a tree with 30 000 parent nodes each having one child.

When RadRichTextBox.IsReasdOnly is true, RadRichTextBox.CommandExecuting is not raised when the user double clicks the header or footer area.

Use attached to reproduce. Broken in version 2018.3.1016.40

Workaround:
private Size minSizeState;
private Size maxSizeState;
protected override void HandleDpiChanged()
{
    //base.HandleDpiChanged();

    float scaleFactor = 1f;

    if (this.oldDpi != 0)
    {
        scaleFactor = (float)this.currentDpi / this.oldDpi;
    }
    else if (this.oldDpi == 0) //Form shown for the first time.
    {
        scaleFactor = (float)this.currentDpi / 96f;
    }

    if (scaleFactor == 1f)
    {
        return;
    }

    this.maxSizeState = this.MaximumSize;
    this.minSizeState = this.MinimumSize;
    this.MinimumSize = Size.Empty;
    this.MaximumSize = Size.Empty;
    
    this.Scale(new SizeF(scaleFactor, scaleFactor));
   
    this.MinimumSize = TelerikDpiHelper.ScaleSize(this.minSizeState, new SizeF(scaleFactor, scaleFactor));
    this.MaximumSize = TelerikDpiHelper.ScaleSize(this.maxSizeState, new SizeF(scaleFactor, scaleFactor));

- remove the space from the text in the formatting event so the text is empty

How to reproduce: 

1. Add a new RadTabbedForm to a VS2017 VB.NET project. 

2. Select the new form in the design view window

3. In the properties box, got to "Tabs" and click the ellipsis (…)

4. The collection editor opens.

5. Click the first tab in the list and change the "Text" property to something new

6. Click "OK"  to save changes

The desired location of the command bar strip elements is saved with a scaled location.

Calling the OffsetView method with a 0 step should return the view currently displayed in the control. At the moment the view is adjusted according to DateTime.Now.

Workaround:
class MyImageEditor : RadImageEditor
{
    protected override RadImageEditorElement CreateImageEditorElement()
    {
        return new MyImageEditorElement();
    }
}
class MyImageEditorElement : RadImageEditorElement
{
    protected override ImageEditorCanvasElement CreateCanvasElement()
    {
        return new MyCanvasElement(this);
    }
}

class MyCanvasElement : ImageEditorCanvasElement
{
    public MyCanvasElement(RadImageEditorElement owner) : base(owner)
    {

    }
    protected override void PaintElement(IGraphics graphics, float angle, SizeF scale)
    {
        base.PaintElement(graphics, angle, scale);

        if (this.IsCropping)
        {
            Rectangle dynamicCropRect = GetCropRectangle();
            SizeF scaleDown = new SizeF(1f / this.DpiScaleFactor.Width, 1f / this.DpiScaleFactor.Height);

            this.AcceptButton.PositionOffset = TelerikDpiHelper.ScaleSizeF(new SizeF((dynamicCropRect.X + dynamicCropRect.Width / 2f) - this.AcceptButton.Location.X - this.AcceptButton.DesiredSize.Width,
                dynamicCropRect.Y + dynamicCropRect.Height - (this.AcceptButton.DesiredSize.Height + 10)), scaleDown);
            this.CancelButton.PositionOffset = TelerikDpiHelper.ScaleSizeF(new SizeF((dynamicCropRect.X + dynamicCropRect.Width / 2f) - this.CancelButton.Location.X - this.CancelButton.DesiredSize.Width,
                (dynamicCropRect.Y + dynamicCropRect.Height - (this.CancelButton.DesiredSize.Height + 10)) - this.CancelButton.Location.Y), scaleDown);
        }

    }
}
