Hi,

Since we want to boost up the performance of the ScheduleView , we've applied the 2023_2_718 UI for WPF to enable the virtualization of the group headers with setting the property  IsGroupHeadersVirtualizationEnabled="True". However we've experienced issues also with rendering for the appointments and group headers(resources) when scrolling.

In one of the screens where the schedule view is used, the group headers don't have equal sizes, for example:

The height may vary depending on the overlapping appointments for the resource which is allowed for our system. 

There is a note that there might be issues and unexpected behavior when the headers have different sizes claimed here:

WPF ScheduleView - UI Virtualization - Telerik UI for WPF

In this scenario we experience multiple issues, like for example when scrolled at the bottom, and the schedule view is fully refreshed, the resources and appointments are not rendered :

until it's scrolled.

Also when scrolling, we experience a "blinking" rendering, the group headers change sizes on scrolling :

Can you please let us know if/when this is planned to be fixed.

Another issue not related to the header size differences is that some of the appointments are lost (not rendered)  when the height of the schedule view is changed resulting in some of the appointments to not be visible anymore .The selection is kept on the group headers, but the appointments are not rendered.

Thank you!

When the VisualizationLayer is populated with FrameworkElement objects (often through the ItemTemplate) and the MapLayer.Location value of a FrameworkElement is updated at runtime, the element itself is not moved to the new location. This happens only if the FrameworkElement is outside of the viewport during the location change action.

To work this around, on location change, remove the data element from the ItemsSource and add it again.

Hello,

I want to report a bug with text color in textbox and presumably in some other controls. When the textbox is edited, then the color is correctly black:

Telerik:   Windows 11 settings textBox: 

But when the textbox loses focus, it changes the color to gray, which is hard to read and looks like disabled:

Telerik:  Windows 11 settings textBox: 

Thanks

Hi,

I download the source code 'Telerik_UI_for_WPF_Source_2022_1_117' and then I want to run 'Build_WPF60.bat' [\Telerik_UI_for_WPF_Source_2022_1_117\Build\BatFiles]. An error occurs, see the attachment: 'Could not locate the assembly "Telerik.Windows.Documents.Core".' I tried it on Win 10 and Win 11 with installed VS202

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

Implement import of bullets and numbering which use the old Word 6.0/Word 95 format from RTF. This includes, but is not limited to, the following RTF tags: \pnlvlN, \pnlvlblt, \pnlvlbody, \pnlvlcont. See RTF specification, "Word 6.0 and Word 95 RTF" heading for full description.

WordPad and some legacy systems export lists with this formatting, so the construction is relatively widespread.

According to the specification, if RTF reader doesn't support specific bullets/numbering tags, it can use the \pntext tag to read the bullets/numbering as plain text; but currently RadRichTextBox always ignores the \pntext tag. Because of this, the bullets or numbers of lists in the old format are missing after import.

When text is using fonts with defined ligatures (e.g. Calibri, Gabriola, etc.) and contains character groups with defined ligature for it, the text width is measured incorrectly (shorter that it should be). As caret and selection navigates on positions computed by this measuring system, they are not synchronized with what is shown in the UI (which correctly respects the ligatures), and there is slight offset from the real character positions and/or clipping of part of the letters at the end of the line.

Examples of such groups are (depending on the font) "tt", "ff", "ffi".

Implement a new LabelFitMode that prevents the axes labels from overlapping by increasing the LabelInteval.
Declined: This is no longer necessary after introducing the SmartLabelsMode.

Hi,

In project we have noticed that sometimes for RadDiagram.ConnectionManipulationCompleted we receive unexpected values in event.

This problem is not systematic but it occurs often at the drag of new connection.

To make it reproducible for you I used CustomConnectors sample project from Diagram.

For easier analysis I recorded a video with bug and changes to CustomConnectors project.

Best regards,
