NullReferenceException is thrown when the RadVirtualKeyboard control gets loaded, but it is not added to the visual tree. This skips the initialization of an internal collection which is used on Loaded, thus throwing the error.

To work this around, you can manually call the OnApplyTemplate method of RadVirtualKeyboard before it gets loaded.

virtualKeyboard.OnApplyTemplate();

The current implementation of the Code128 symbology class used with RadBarcode throws an InvalidSymbolException for characters with codes greater than 127.

As you can see from this table, there are many special characters in Code128 that have larger codes:

https://en.wikipedia.org/wiki/Code_128#Bar_code_widths

It would be useful to have these in applications which need to modify a reader device's behavior with barcode control characters in order to communicate properly.

It seems that the first time a Center TextAlignment is applied to the selection, its length is cached. Because of this, when the selection content (text) changes the length is not updated, thus the text doesn't align properly. It aligns accord to the initial length of the context. The content doesn't update also if the alignment is reset.

 

To work this around, avoid the FlowNoWrap layout mode and use only Flow.

After upgrading to .net 9 I get the following error when starting the published program (running it in RIDER in debug-mode doesn't create the issue).

(The issue might be similar to: https://feedback.telerik.com/wpf/1670420-typeinitializationexception-in-telerik-windows-input-touch-touchmanager-with-net-9 )

Fixed in Telerik.Licensing NuGet package version 1.4.10. Install this (or later) version of the package to avoid the issue.

Build errors may occur in situation where you have two projects one depending on the other, and the main project installs the Telerik.Licensing nuget package. The package triggers a set of MSBuild taks and at some point an IncrementalClean is invoked, which deletes some of the files and errors occur during the build.

The error message that can occur:

 

CSC : error CS0006: Metadata file 'dll/file/path/here.dll' could not be found [project directory path here]

Currently RadComboBox supports filtering of the data when IsEditable is True. 

Add a mode where a search box is displayed (when IsEditable is False) in the drop down of the control.  The searchbox should filter the items in the dropdown.

The issue seems related to an animation timing problem in combination with the internal usage of the ObjectAnimationUsingKeyFrames class instead of BooleanAnimationUsingKeyFrames.

The exception message is: 

 

Cannot animate the 'IsEnabled' property on a 'System.Windows.Controls.ContentControl' using a 'System.Windows.Media.Animation.ObjectAnimationUsingKeyFrames'.

 

The exception stacktrace:

System.Windows.Media.Animation.AnimationException: Cannot animate the 'IsEnabled' property on a 'System.Windows.Controls.ContentControl' using a 'System.Windows.Media.Animation.ObjectAnimationUsingKeyFrames'. For details see the inner exception.

To work this around, you can extract the ControlTemplate of RadBusyIndicator and replace the ObjectAnimationUsingKeyFrames that animates the ContentControl.IsEnabled property with a BooleanAnimationUsingKeyFrames.

 

	<BooleanAnimationUsingKeyFrames BeginTime="00:00:00" Duration="00:00:00.001" Storyboard.TargetName="Content" Storyboard.TargetProperty="(Control.IsEnabled)">
		<DiscreteBooleanKeyFrame KeyTime="00:00:00">
			<DiscreteBooleanKeyFrame.Value>
				<sys:Boolean>False</sys:Boolean>
			</DiscreteBooleanKeyFrame.Value>
		</DiscreteBooleanKeyFrame>
	</BooleanAnimationUsingKeyFrames>

Currently, the RadGanttView control displays an indicator in the timeruler area of the control. Allow stretching the time indicator accross the timeline area where the tasks are rendered (under the timeruler).

Many document elements (like Footer, Header, Note, Comments, etc.) have their own RadDocument instance that serves as their body. These child documents are part of the main RadDocument assigned as the Document of RadRichTextBox.

Currently, to access the child RadDocument elements, you should iterate each different element of the main RadDocument and collect its Body property value.

Add a method to easily collect the child RadDocuments, similar to how the EnumerateChildrenOfType<T> method works. Currently the EnumerateChildrenOfType<T> method doesn't work for searching RadDocument, so you can consider extending this already existing API.

Hello together,

I am experiencing a bug with the following use case:

  1. Import an existing PDF file
  2. Modify the PDF file
  3. Export the PDF file

When upgrading Telerik.Documents.Fixed from version 2024.3.806 to version 2024.4.1106 the exported PDF file is missing different parts of the originally imported PDF file or even results in a complete "messy" file. Input and output files are view with Adobe Acrobat, Google Chrome, Edge...all showing the same result.

Even omitting step 2 (i.e. I only import and directly export the PDF file) results in the same bug after.

I do not use any special import or export setting to reproduce the error. But even with applying different import/export settings I could not change the buggy outcome.

 

var bytes = File.ReadAllBytes(@"C:\temp\in.pdf");
var formatProvider = new PdfFormatProvider();
var document = formatProvider.Import(bytes, TimeSpan.FromSeconds(20));
var outBytes = formatProvider.Export(document, TimeSpan.FromSeconds(20));
File.WriteAllBytes(@"C:\temp\out.pdf", outBytes);

See the attached file for example, import it and export it (via code snippet above).

With version 2024.3.806 everything works fine - and as I am not seeing any relevant breaking changes or other release information regarding this issue, I am a little bit lost with what I could do to solve the issue..

Thanks for your support!

The following exception is raised when adding a ColumnGroupDescriptor to the GroupDescriptors property of a RadGridView.

NullReferenceException is thrown when the document gets updated after TableRow objects were removed with the Remove method of the parent Rows collection of the Table.

The table.Rows.Remove method is not properly removing some of the rows.

To work this around, use the DeleteTableRow method of the RadDocumentEditor.

RadDocumentEditor documentEditor = new RadDocumentEditor(document);
documentEditor.DeleteTableRow(row);
