Hi, I have a problem with using SyntaxEditor. 

There are two errors when using Korean.

1. When I enter Korean, the caret is shown to the left of the position to be entered. (See line 19 in the Attached File 1)

To add a description of the attached file1, it was a situation in which "가나다라마바사아자차카타파하" was entered in the order, and "하" is the last letter entered, but it can be showed that "하" is located in the middle between "사" and "자". (See line 19 and I check this character with green border in the Attached File 2)

2. When Korean is present in the line, the length of the selection area represents shorter than the input width of the input characters when selected. (See line 3, 19, 20, 21, 27, 28 in the Attached File 3)

I found that the same defect occurred in Windows11 and Windows10.

I hope it will be resolved as soon as possible.
 

Hi,

it would be convenient to add an extra small font size to te existing enumerations. For instance in Windows 11 theme, could it be possible to add a XS size:

Windows11Palette.Palette.FontSizeXS = 10;
Windows11Palette.Palette.FontSizeS = 12; 
Windows11Palette.Palette.FontSize = 14; 
Windows11Palette.Palette.FontSizeM = 18; 
Windows11Palette.Palette.FontSizeL = 20; 
Windows11Palette.Palette.FontSizeXL = 28; 

Having a range in the bigger font sizes is very useful. It owuld be equally helpful to have a range on the smaller font.

Thank you for considering it :)

Currently PropertyDefinitions have only one Property for DataBinding, which is very strange solution.

All these instances are DependencyObject, but at the same time they are not in the visual tree and we could not bind to a visibility or to readonly or to any other property without some starnge sorkarounds (why this was designed in this way?).

This makes these objects almost useless. becuae we cannot fully use them in an MVVM way (bindings, multiibindings, etc.)

Possible solutions:

1. provide bindings for all properties to make them be bindable withput any workarounds
2. Change PropertyDefinitions to something that will live inside visual tree.

We use a RadTreeView with many different item types that set a DefaultImageSrc based on a combination of item type and state
(from each item's view model).

For the currently selected TreeView item we would like to modify the item's image with a coloured border.
So it would be a very useful feature, if the TreeView item's SelectedImage could be derived from the DefaultImageSrc
via XAML Shapes (Rectangle, Line, etc.).
(Shapes can e.g. already be used to draw TreeView's Expander-Button for expanded/collapsed state, which is very useful).

Currently the only approach is to copy any item-type's image in the file system and modify it for selected state.
(Thus doubling the number of item image files.)
Given the number of images for different item types and states that we already have, this is not very practical.

Examples for DefaultImageSrc (left) and SelectedImageSrc (right):

•  -> 
•  -> 

Is it possible to extend RadTreeView, so that the SelectedImageSrc can be based on the given DefaultImageSrc, but with a modification provided via XAML?

HeaderSizeNeeded is fired twice with the same index and affects the header row width. 

Hello,

I use RadPdfViewer to view a PDF file in my WPF application, the PDF file has only one page and the contents are in the middle of the page, so I'm trying to zoom and focus on the middle of the page, I use the following code:

private void DocumentChanged(object sender, DocumentChangedEventArgs e)
        {
            pdfViewer.ScaleFactor = 1.3;
            var size = pdfViewer.Document.Pages[0].Size;
            pdfViewer.ScrollToVerticalOffset(size.Height * 0.3);
            pdfViewer.ScrollToHorizontalOffset(size.Width * 0.20);
        }

however, I only see the horizontal scroll working.

How can I zoom then scroll to vertical and horizontal offset?

i hope add char   controls

like :

Right now, it is not easy to disable styles for standard controls like Button.
Especially when using NoXaml.

You have to create an Empty style on Application level for the control to "rewind" its style.
I do believe this kind of style drags down performance of controls when unloading, since it causes StyleChanged events.

Some explanation about performance (how things work to my understanding). Might be BS, but I spend a few hours debugging through .net code to get this idea:

Issue is, that when control is unloaded, its not part of the logical / visual tree of the application anymore, so it falls back to styles defined on assembly level.
e.g. Themes/Generic.xaml.  So the empty styles defined on Application level do not count anymore, but the ones you defined in your theme.
This can be observed on RadTabbedWindow. When unloading pages (like switching between them), controls fall back to the styles defined in the theme from Telerik.Windows.Controls.Navigation, because they are still children of that page.
You can observe this behaviour if you set a Breakpoint in FrameworkElement.OnStyleChanged before unloading a control tree.

If you'd remove the System.Windows.xaml from your theme-dictionaries so that one can decide to merge those styles or not, that would be great.

Hi

I would like to know if Progress Telerik has some plan to port their WPF controls to Avalonia (avaloniaui.net).

Thanks

Hi:

China has the largest population and we have a lot of Chinese customers. Increasing support for Chinese localization, IME and bug fixes should be a high priority.

Unfortunately, there are still no support plans for many features. In the Chinese environment, there are still many bugs.

Hope can be taken seriously！

There is too much unplanned feedback, not just in Chinese, but also in Japanese and Korean. These should be viewed as a single issue and considered a serious one.

That's more than enough votes. The following should be combined。

Hi,

our company is slowly rolling out high-DPI laptops to our users. On such devices, Windows automatically enables DPI scaling, using a value of 125% or 150%, depending on the screen's resolution. In combination with an external (unscaled) monitor, this causes our application, to appear blurry on the scaled screen.

Windows has built-in functionality to reduce the blurring, however, this only works on the main screen. If you connect a secondary screen and set that as your main screen, the application will always appear blurry on the laptop screen.

My understanding of the topic is that WPF is DPI aware - but on the system level. So it does not cope well with monitors that have different DPI settings. However, I found a tutorial on Microsoft Docs (https://docs.microsoft.com/en-gb/windows/win32/hidpi/declaring-managed-apps-dpi-aware?redirectedfrom=MSDN), hinting that it is possible to make WPF windows per-monitor DPI aware. Unfortunately, this workaround requires you to inherit your window class from their utility class.

Since all of our windows already inherit from RadWindow, I have no chance to include this without copying either their base class or RadWindow. Having RadWindow support per-monitor DPI awareness would be a great feature to have. Or is there already a way to support this?

PS: Why does the first feature form in the feature request workflow (the one, where it first searches for similar requests) not let me select the control/area I am searching for like the one for private tickets? I almost submitted this request for the Area "All (Multiple Controls)" because of that.

Default keystroke in other editors to activate text replacement is: ctrl+H

Would be nive to enable this in the syntax editor.

Good afternoon,

When we add a new child element to the RadDiagram(see attach file), the diagram automatically optimizes their layout. After the chart is updated, the new element and its parent are automatically moved to the left side. How to make them stay in their places?

There is a small discussion of this problem on the forum.

I would like the possibility to change the color of a line depending on the value.

For example:

I have values between -1 to 10.

If the value is -1 I would like the color (or possible the opacity) to change until it goes back to 0 or above.

As far as I know, there are no way to set the color of the title bar. As far as I know there are no properties "color" of the title bar.

Thanks
