Type in Japanese text in RichTextBox that word wraps beyond the first line and export it to PDF. The text should always be left aligned (as visually shown when typing) but has an "indent" when exported when the font is Segoe UI.
When adding a button cell as below, if the button cell is selected the button doesn't work when tapping it.
<telerik:GridViewDataColumn Header="Config"

telerik:TouchManager.TouchMode="None"I have attached a sample project in which the error occurs, simply tap a button, close the MessageBox and tap the same button again. Thank you for your time!
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);
If a RadDocking has its theme set to Windows 11 via the StyleManager.Theme attached property, placing a RadGridView inside (styled with a different theme, such as Office_Black, Summer, etc.) will cause its cells to look merged after performing an edit operation.
As a workaround, the RowHeight and the FontSize properties of the RadGridView instance can be used to resolve this.
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 :)
Hi
I would like to know if Progress Telerik has some plan to port their WPF controls to Avalonia (avaloniaui.net).
Thanks

Hi!
Iam trying to use a RadGauge to display two values, CurrentCapacity and MaxCapacity, and I thought a gauge would be a nice way. But my marker on the RadHorizontalLinearGauge does not align correctly.
<telerik:RadHorizontalLinearGauge>
<telerik:HorizontalLinearScale Min="0" Max="10" >
<telerik:HorizontalLinearScale.Indicators>
<telerik:Marker Value="2"></telerik:Marker>
</telerik:HorizontalLinearScale.Indicators>
</telerik:HorizontalLinearScale>
</telerik:RadHorizontalLinearGauge>Results in:
Notice marker is not on 2. The same problem occurs with different Max and Values.
Do I have some strange style that applies a margin/padding or something?
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:
- provide bindings for all properties to make them be bindable withput any workarounds
- Change PropertyDefinitions to something that will live inside visual tree.
Using RadTabbedWindow I noticed difficulty dragging maximized windows between monitors. It seems to happen in multi-monitor environments and only when dragging Left of the PrimaryScreen.
In the video I've included , the blue window is a standard window and can be maximized in one drag across any display.
The white window is RadTabbedWindow and the drag will default to the PrimaryScreen when dragged to the left-most display.
Any help would be appreciated. Thanks
SelectedItems collection not updated when items are removed
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?
I have no idea how to reproduce this, but every so often after a paste operation into a RadRichTextBox, the host thread becomes unresponsive to user input. The message pump is still running but the following unhandled exception gets thrown in a tight infinite loop. The only way to close the window is to right click on the taskbar button.
System.NullReferenceException
