The form fields are not displayed when loading specific pdf files.

Scrolling performance in large spreadsheets is significantly worse when auto filters are enabled.

RadMaps Silverlight BingMap provider stopped displaying tiles in 2022 due to change in Bing Maps service.

Either workaround or statement regarding the future of this feature is needed.

RTF documents that do not define the appropriate style types in the style definitions are not processable in RTB. While this is a deviation from the standard, MS Word manages to fix them and then open them.

When the MinTimeRulerExtent of a view definition is lowered (to the point that the view does not have a scrollbar) and the EnableSmallAppointmentRendering is true, the content of the group headers is not displayed. 

 

Here is the error:

Invalid XmlnsDeclaration occurs in assembly 'Telerik.Windows.Controls.GridView, Version=2018.3.1016.1050, Culture=neutral, PublicKeyToken=5803cfa389c90ce7'. XmlnsDeclaration references a namespace 'Telerik.Windows.Controls.MultiColumnComboBox' that is not in the assembly.

It is reproducible only in Visual Studio 2010 SP1.

Some documents containing embedded jpeg images with DCTDecode filter are not decoded correctly in RadPdfViewer for Silverlight

At this point not much else is known other than the stack trace. The stack trace suggests that this happens on selection done by dragging the mouse and perhaps the document is with incorrect structure.

When the user opens a dialog in RadRichTextBox, after closing this dialog, the focus is lost.

When a hyperlink is copy/pasted from MS Word to RadRichTextBox, only the display name is pasted and the hyperlink is lost.

The textblocks in PageSetup dropdowns in PageLayout tab have black foreground, when Expression_Dark theme is applied. The foreground color should be white.

If RadSpreadsheet is shown in RadWindow or in Popup, Filtering dialog throws NullReferenceException.

The reusable Form XObject content always resets its GraphicState color property. Instead, it should take the current GraphicState color from the content stream. This may result in wrong colors.

The character mapping cannot find the character with name "checkbld" and the glyph is not visualized.

The exception can be observed when printing document containing images with unsupported formats, or images with empty source (RawData = "").

The exception is with the following call stack:

   at Telerik.Windows.Documents.UI.HeaderFooterContainer.UpdateUI(SectionLayoutBox sectionBox, Boolean delayed)
   at Telerik.Windows.Documents.UI.HeaderFooterContainer.UpdateUI(SectionLayoutBox sectionBox)
   at Telerik.Windows.Documents.UI.DocumentPrintPresenter.MeasureOverride(Size availableSize)
   at System.Windows.FrameworkElement.MeasureOverride(IntPtr nativeTarget, Single inWidth, Single inHeight, Single& outWidth, Single& outHeight)


Workarounds:

If you click on print preview and print the document from the preview it is working;
     2. Use the following code

        this.radRichTextBox .PrintStarted += Rtb_PrintStarted;

        private void Rtb_PrintStarted(object sender, EventArgs e)
        {
            RadRichTextBox rtb = (RadRichTextBox)sender;
            foreach (var floatingImage in rtb.Document.EnumerateChildrenOfType<FloatingImageBlock>()
                                                      .Where(fi => !this.IsSupportedImageFormat(fi.ImageInline.Extension))
                                                      .ToList())
            {
                floatingImage.Parent.Children.Remove(floatingImage);
            }

            foreach (var inlineImage in rtb.Document.EnumerateChildrenOfType<ImageInline>()
                                                    .Where(i => !this.IsSupportedImageFormat(i.Extension))
                                                    .ToList())
            {
                inlineImage.Parent.Children.Remove(inlineImage);
            }
        }

        private bool IsSupportedImageFormat(string format)
        {
            return (format == "jpg") ||
                   (format == "jpeg") ||
                   (format == "png") ||
                   (format == "bmp");
        }   

The calculation of the left and hanging indent is incorrect for paragraph in list when the left and hanging indents are with the same value.

Italic bullet sign of bulleted paragraph (with last italic characters) is exported like an equal sign with a line through it.

Workaround: Make all italic bullets non-italic. The following code achieves that:

RadDocument document = this.radRichTextBox.Document;

foreach (var paragraph in document.EnumerateChildrenOfType<Paragraph>())
{
    if (paragraph.ListId != Paragraph.ListIdProperty.DefaultValue)
    {
        DocumentList documentList = document.ListManager.GetDocumentListById(paragraph.ListId);
        int levelIndex = paragraph.ListLevel != Paragraph.ListLevelProperty.DefaultValue ? paragraph.ListLevel : 0;

        if (documentList.ActualStyle.Levels[levelIndex].NumberingFormat == ListNumberingFormat.Bullet)
        {
            documentList.ActualStyle.Levels[levelIndex].SpanProperties.FontStyle = FontStyles.Normal;
        }
    }
}

this.radRichTextBox.UpdateEditorLayout();
