The search functionality is inconsistent in Unbound Mode. Typing a word highlights all rows that contain that word or string, as expected. However, if the cursor is moved and additional characters are typed at the beginning of the search box, no results are returned, even if matching rows exist that contain the updated string combination.

The same behavior is not observed in bound mode.

Add a property that can control whether a table row is allowed to break across pages or not.

When I show some text and set IsWordWrapEnabled to true... the horizontalscrollbar disappears


but when I set IsWordWrapEnabled to false after this, the horizontalscrollbar does not appear 

in your code I saw this:

                ScrollBarVisibility newScrollVisibility = editor.IsWordWrapEnabled ? ScrollBarVisibility.Disabled : ScrollBarVisibility.Auto;
                editor.SetValue(HorizontalScrollBarVisibilityProperty, newScrollVisibility);

But this .Auto property doesn't seem te work. 
Further more, next to this problem, I'd like to set this horizontalscrollbar to appear and disappear depending on the text width...
but I'm afraid this would be depending on the .auto property

 

Open the "First Look" demo app for rich text editor. Delete all the text. Insert a table with 5 columns and 2 rows. Select first 2 columns (4 cells in total). Merge these cells. The merged cell should have the width of 2 normal columns. Save this document as RTF. Open the document. The width of all columns is wrong. The merged cell now is wide as one normal column.

It seems that two issues are combined into one problem. First, two merged columns are converted into one column. If I try to split the merged cell before the save I get my two columns back, but after the save there are only two rows after the split, but only one column. Second, the "AutoFit to Window" option is messing with the column widths. If I set the table to "Fixed Column Width" then the table remains unchanged after reload. But this option doesn't work if the merged cell is selected. Must unselect it first, or change the option before the merge. But this minor annoyance is not the part of this bug report.

In this scenario, the scrollbars are shown on an empty document when the form is moved to HDPI monitor.

Overview

This repository documents a bug found in the Telerik PDF Viewer control for Windows Forms. The issue specifically affects the rendering of SVG graphics embedded in PDF files, where the stroke-width attribute is ignored by the viewer.

Affected Component

• Product: Telerik UI for WinForms
• Control: `RadPdfViewer'
• Version: 2025.01
• Platform: Windows Forms (.NET Framework)

Description of the Issue

When a PDF file contains an embedded SVG graphic that utilizes the stroke-width CSS property (or SVG attribute), the stroke width is not rendered correctly in Telerik's PDF preview control. Regardless of:

• Unit used (e.g., px, pt, em, %, etc.)
• Value assigned (e.g., stroke-width: 5, stroke-width: 30, etc.)

…the resulting line always appears thin, as if the stroke width were ignored entirely. This makes the SVG appear incorrectly and inconsistent with its rendering in other PDF viewers (e.g., Adobe Acrobat, Chrome's built-in viewer).

Steps to Reproduce

1. Run the application from provided MCVE
2. Observe the SVG lines in PDF preview: all strokes appear thin, regardless of defined stroke width.

Expected Behavior

The Telerik PDF viewer should correctly honor and render the stroke-width property defined within SVG elements embedded in the PDF file.

Actual Behavior

All strokes in SVGs appear very thin, with no visual difference despite varying stroke widths in the source SVG.

Sample Files

• ✅ _PdfExample.pdf: A PDF with SVG lines that render correctly in Microsoft Edge.
• ✅ _PdfExample.pdf: Screenshot of how the PDF file looks in Microsoft Edge.
• ❌ _ScreenshotFromTelerik.png: Screenshot of how the same file looks in the Telerik PDF Viewer (note the thin lines).
• 🔍 _LargeStroke.svg, _SmallStroke.svg: The original SVGs used in the PDF file.

Environment

Component	Version
Telerik UI	2025.1.211.48
.NET Framework	.NET Framework 4.8
OS	Windows 11

Suggested Fix

Ensure that the rendering engine used by RadPdfViewer fully supports the SVG stroke-width attribute when parsing and rendering embedded SVG content.

This behavior is related to how the control is measured while using the MS Form. In the given scenario, the control has many columns, and some of them are pinned. Moving to the last column and typing in the filter cell will filter the rows in the column. However, when filtering, if the row number is less than the viewport, the vertical scrollbar will disappear as it is not needed anymore, and the filter editor will be placed in the wrong column. This will mess with the filter cell editor. 

Implement UIAutomation.

 

The problem is, that the "Activated" sub of another form was fired after the overlay was closed.

The EnableHotTracking property works only in the first level hierarchy. The lower levels still get highlighted.

The StepClicked event should trigger when a RadStepProgressBarItem is clicked.

 

We can create a FloatingActionButton similar to the one in Telerik UI for ASP.NET Core.

AllDay event is rendered on two days when using different TimeZone for SystemTimeZone with DefaultTimeZone

Appointments Start/End date is wrong when using different TimeZone for SystemTimeZone with DefaultTimeZone. Appointments are placed in the wrong date or the start/end properties are wrong in the EditAppointmentDialog.

Slow performance of the control runtime, which also slows down VS debugger

In this case, we have numeric values shown as a string in a GridViewTextBoxColumn. If we use the RadFilterView settings, we can filter by one item only. If we choose to filter by more than one, it will lead to an empty grid.
