Hello there,

I am facing system.StackOverflowExcepiton while exporting document with HtmlFormatProvider. I am attaching my code with the HTML string which I am passing into RichTextEditor.

---------------------------------------------------------

HTML String:

"Navigate to the <a href="https://exelon.ifs.cloud/landing-page/" target="_blank"><b><u>IFS Cloud Landing Page</u></b></a>.<br /> <br />NOTE: If the above link does not work for you, copy and paste this address ...<br /> <br /><u>https://exelon.ifs.cloud/landing-page/</u>"

Method which is giving me an error:

We are using the DropDownButtonElement on a RibbonBar, there are a very frustating issue with the RadArrowButtonElement.

On this image it show 5 children, but on code there are 6 children, here is a CopyPase of your  CreateChildElements in RadArrowButtonElement.

    protected override void CreateChildElements()
    {
        arrow = new ArrowPrimitive(ArrowDirection.Down);
        arrow.Class = "RadArrowButtonArrow";
        arrow.AutoSize = false;
        arrow.Alignment = System.Drawing.ContentAlignment.MiddleCenter;
        overflowArrow = new OverflowPrimitive(ArrowDirection.Down);
        overflowArrow.Class = "RadArrowButtonOverflowArrow";
        overflowArrow.AutoSize = false;
        overflowArrow.Alignment = System.Drawing.ContentAlignment.MiddleCenter;
        overflowArrow.Visibility = ElementVisibility.Collapsed;
        fillPrimitive = new FillPrimitive();
        fillPrimitive.Class = "RadArrowButtonFill";
        fillPrimitive.AutoSizeMode = RadAutoSizeMode.FitToAvailableSize;
        borderPrimitive = new BorderPrimitive();
        borderPrimitive.Class = "RadArrowButtonBorder";
        borderPrimitive.AutoSizeMode = RadAutoSizeMode.FitToAvailableSize;
        imagePrimitive = new ImagePrimitive();
        imagePrimitive.Class = "RadArrowButtonImage";
        imagePrimitive.AutoSizeMode = RadAutoSizeMode.FitToAvailableSize;
        imagePrimitive.Alignment = System.Drawing.ContentAlignment.MiddleCenter;
        textPrimitive = new TextPrimitive();
        textPrimitive.Class = "RadArrowButtonTextGlyph";
        textPrimitive.AutoSizeMode = RadAutoSizeMode.FitToAvailableSize;
        textPrimitive.TextAlignment = System.Drawing.ContentAlignment.MiddleCenter;
        textPrimitive.StretchHorizontally = true;
        textPrimitive.StretchVertically = true;
        Children.Add(fillPrimitive);
        Children.Add(borderPrimitive);
        Children.Add(arrow);
        Children.Add(overflowArrow);
        Children.Add(imagePrimitive);
        Children.Add(textPrimitive);
    }

The problem is that we are changing the ArrowButton size to (6, 0) width, here is the how it looks:

As you can see the triangle is outside the ArrowButton, my first idea was to look the ArrowPrimitive and OverflowPrimitive, but that triangle is on TextPrimitive.

Making this change on RadDropDownButtonElement i was able to "solve" the offset and the size.
base.ArrowButton.TextPrimitive.Font = new Font(base.ArrowButton.TextPrimitive.Font.FontFamily, 6);

I have to comment this to something like: "I dont know why this works, but the triangle is on a child text primitive... So don't erase this line".

When Telerik UI for WinForms / WPF extensions are installed, Visual Studio is unresponsive for a couple of minutes after a solution is loaded. During that time, "Updating source control status…" is shown.

Workarounds:

• Disable Telerik UI for WinForms / WPF extensions.
• Checkout the solution file.

Setting the Title property should update the header text:

 this.radPageViewPage1.Title = "test";

Currently, RadPdfViewer offers the DataError event which is purposed to handle errors during the import process. However, if there are problematic pages that are rendered in the viewer at a later moment after the document is already imported, the viewer doesn't offer a suitable way for handling such problematic moments even though the PdfProcessing library throws one of its exceptions. 

The exact client's case is loading a PDF document which contains images requiring JPX Decoder which is currently not supported. Even though the PdfProcessing library throws internally the following error, the RadPdfViewer control doesn't throw the DataError event with the respective error:

Telerik.Windows.Documents.Fixed.Exceptions.NotSupportedFilterException: 'JPXDecode is not supported.'

Hi Team,

I would like to request to add a Today button to the RadDateTimePicker so when the user clicks on it, the value of the RadDateTimePicker will be set to the current day/time.

Thank you!
