A specific file is not displayed in the viewer.

In a multi monitor scenario with different scalings and an application that is configured to run ‚per monitor dpi awareness‘ a floating toolwindow cannot be docked at all positions.

Example:

Monitor 1: 1920 x 1200 (100%), Monitor 2: 2048 x 2560 (150%)

Our WPF application has a main window, maximized on screen 1 and a child window maximized on screen 2.

In the app.manifest we use per monitor dpi awareness.

Both windows have a RadDocking instance with a docked RadPane. Start the application, undock a tool window and try to dock it at the right position on monitor 1.

è It is not possible since the compass is deactivated before the mouse cursor reaches the right monitor area.

 

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).

System.TypeInitializationException: The type initializer for 'Telerik.Windows.Input.Touch.TouchManager' threw an exception.
 ---> System.IO.FileNotFoundException: Could not load file or assembly 'System.Windows.Forms, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. Das System kann die angegebene Datei nicht finden.

 

the mentioned assembly System.Windows.Forms is not used by me at all.

Suddenly with WPF release 2024 Q4 some of pdf-s are not presented correctly. Attached file was produced with Telerik Report Designer and exported as pdf. With previous WPF version was OK.

You can check in your demo application. It is shown in previous release but not with latest.

Please make solution ASAP.

Hi, we have many documents (drawings) and these documents are full of stamps. Unfortunately the pdfviewer does not show them.

I am only asking for rendering stamps properly, not creating or modifying. I want to see the stamps. I also see that some stamps are rendered, not all, but some and they are displayed off the document. as if they were rotated 90deg. If no support is added, at least correct the position they are displayed at.

I have attached two pictures, one opened in Adobe and one with the viewer in my app.

 

Please consider at least fixing the display, even if no support for stamps is provided. Just display it correctly. By the way the stamps have not been flattened. that is intentional.

 

Thanks,

Hi, this document is displaying the stamps in the wrong place. I am using this tool to load drawings published by Adobe and Autocad. The stamps that are added later do not display properly. Using Windows 10 and Windows 11, also lates Telerik Componets just released. 2024 for WPF. Please see attachment for testing.

TabControl: The tab items and their content are not disposed correctly due to the RadTabItemAutoamtionPeer.

Using the mouse to select text inside the `PdfViewer` does not correctly select the text, sometimes it even selects the text of the next line.
The visual indicator of the selected area is slightly above the text as you can see in the attached screenshot.


You can find a fully reproducable example in the attachments

When the focus gets in RadRichTextBox, AutomationProperties.Name is not pronounced by screen readers (for example by Windows Narrator).

Add support for successful typing text with IME - Chinese, Japanese, Korean etc.
Currently there are input issues, selection issues, caret issues when using IME input.

Currently, when a RadAutoCompleteBox is placed in a ScrollViewer, the inner ScrollViewer of RadAutoCompleteBox prevents the parent one from scrolling via the mouse wheel.

Here's an idea for you, one which I haven't fully thought through but which I will post here in case it proves useful.

For my use case we am required to build the Telerik UI for WPF binaries from the source code. This is because we offer our product as a trial version which requires the source files to be protected.

Building the source takes a bit of time whenever there is a new version and we have to remember to copy and replace the modified source protection files before we build the binaries.

My suggestion would be to move the file protection code into a single separate class library (DLL) and provide the source code that can be modified by the end user and rebuilt into the file protection DLL.

Then rather than having to rebuild the entire source code from scratch whenever there is a new version, we could just use the installer to install the new binaries and just replace the FileProtection.dll file.

That way when there is a new version of UI for WPF (or whatever product) we could quickly update to it and then when we build our product installer we just copy the modified FileProtection.dll to be bundled alongside the Telerik binaries.

As I said I haven't thought this through all the way and there may be excellent reasons why you are unable to do this, but I thought I'd share the idea.

I have a GridView, with  ClipboardCopyMode set to "Cells, Header" and defined event CopyingCellClipboardContent :

private void RadGridView1_CopyingCellClipboardContent(object sender, GridViewCellClipboardEventArgs e)
{
// _excludedcolumns = columns excluded from copy operation set in logic before
if (_excludedcolumns.Contains(e.Cell.Column))
{
e.Cancel = true;
}
}

Header cells are empty, not skipped like ordinary cells.

Its been two years since you were last asked for this, and you said when it gets traction. 

Well, its getting traction, v11 is coming out, there is ever increasing list of public projects, https://avaloniaui.net/Showcase, plus countless WPF inhouse migrations like the ones we do. Serious money is already being involved, there are already many teams who would rather pay you for controls than waste their own cycles repeatedly making functionality. 
WPF is indeed dying, .net foundation is treating it like a leprous uncle, Avalonia is literally getting more love from some foundation projects than WPF does, some wpf libraries are still targeting net5 with no intention to update them. MS wants you to migrate away from it to MAUI (after failing to get us to migrate to UWP) and it lacks cross platform support which neither of MS replacements like MAUI offer, and MS has a big influence over what they do. Chances of that succeeding are very slim, as big as they were for UWP. Even barring the lack of Linux support, WPF has this pre-mortem smell that Silverlight had, people stick to WPF becuase there really is no roadmap that will retain full functionality.

Chicken and the egg debate is losing its appeal, we are presently even willing to sacrifice some functionality to get away from WPF before it sinks. 

The writing is on the wall, there is a clear and present need for quality commercial 3rd party controls for Avalonia, from the paying customers. I understand there is work to port the styling in WPF controls and to remove any windows P/I dependencies you might have. But whoever of you largest control makers steps on the market first and opens the flood gates, will get the first revenue and a foot in the porting of larger WPF projects, and certainly the inertia going forward.  I am posting this to each of you. 



Time to wake up. "Wake up and smell the ashes" :)

Missing a single character from the digital signature with a specific document.

A specific file cannot be printed with the new engine

When importing a document containing a formula with an invalid reference an exception is thrown: FormulaParseException: 'Unused input [A1] after attempting to parse the formula [#REF!A1]'

According to the Open XML documentation, the possible max value for this attribute is an unsignedInt or 4294967295.

I want to be able to specify the font family, size, etc. from XAML, not from code. 
Exactly the same as described here:
https://www.telerik.com/forums/implicit-styles-custom-font-and-font-size

(background: We are developing a UI Framework + resource dictionary for use in different applications. If each app will have to modify font sizes from code, inconsistencies are surely happen)
