Hello everyone,
Here are the highlights of the new online resources we published this week from 10 Nov 2025 to 17 Nov 2025:
Article: https://docs.telerik.com/devtools/winforms/knowledge-base/add-license-key-in-add-in-project
Summary: This article explains how to add the Telerik UI for WinForms license key in an add-in project (e.g., VSTO/COM) to avoid runtime licensing errors. It shows where to register the key during add-in startup and how to embed the license file as an Embedded Resource so the license is applied before any Telerik controls are instantiated.
Article: https://docs.telerik.com/devtools/winforms/controls/pdfviewer/features/ai-summarization
Summary: RadPdfViewer for WinForms supports AI summarization of PDF content, allowing you to generate summaries for the entire document or the currently selected text. You configure an OpenAI or Azure OpenAI provider (API key and model), enable the built-in summarization UI/commands, and customize prompt templates to control the output for your use case.
Article: https://docs.telerik.com/devtools/winforms/knowledge-base/calendar-add-custom-space-footer
Summary: Learn how to add a custom footer area to RadCalendar in Telerik UI for WinForms by extending the control and injecting a LightVisualElement into its element tree to reserve space at the bottom. The article shows how to set a fixed height, align the footer, and update layout so the footer persists across theme and view changes, letting you host custom content (labels, buttons) beneath the calendar.
Article: https://docs.telerik.com/devtools/winforms/knowledge-base/chat-intercept-html-links
Summary: This article shows how to intercept and handle HTML anchor links inside Telerik UI for WinForms RadChat messages by using the MessageFormatting event to access the message’s markup text element and subscribing to its LinkClicked/HyperlinkClicked event. It demonstrates capturing the clicked URL and executing custom logic (for example, open in a browser or cancel navigation) so you can control link behavior per message.
Article: https://docs.telerik.com/devtools/winforms/knowledge-base/chat-resize-wrap-text-cardaction
Summary: This article shows how to make RadChat CardAction text wrap in Telerik UI for WinForms when the control is resized. You implement a custom ChatElementFactory that returns a CardAction element with TextWrap enabled and width-aware measuring (e.g., updating MaxSize on SizeChanged), so long labels break across lines and the card layout reflows correctly.
Article: https://docs.telerik.com/devtools/winforms/knowledge-base/datetimepicker-customizing-footer-panel
Summary: This article shows how to customize the footer panel of the popup RadCalendar used by the Telerik WinForms RadDateTimePicker. You’ll access the calendar’s footer element when the drop-down opens, hide or rename the default Today/Clear buttons, add custom RadButtonElements, wire Click handlers to set the picker’s Value, and close the popup programmatically.
Article: https://docs.telerik.com/devtools/winforms/knowledge-base/grid-custom-filtering-self-referencing-hierarchy
Summary: This article shows how to implement custom filtering in Telerik WinForms RadGridView when using a self-referencing hierarchy (Id/ParentId). You will handle GridViewTemplate.CustomFiltering to evaluate matches across levels, keep parent rows visible when any child satisfies the filter (and optionally the reverse), and preserve the hierarchical structure while applying FilterDescriptors.
Article: https://docs.telerik.com/devtools/winforms/knowledge-base/gridview-snap-one-row-per-scroll
Summary: Learn how to make RadGridView (Telerik UI for WinForms) snap the viewport to full rows, scrolling exactly one row per mouse wheel action. The article shows intercepting MouseWheel to suppress the default pixel-based scroll and using TableElement.RowScroller APIs (optionally aligning VScrollBar.SmallChange to the row height) to implement discrete, row-based scrolling.
Article: https://docs.telerik.com/devtools/winforms/controls/navigationview/kb-related-articles
Summary: This page indexes Knowledge Base articles for the Telerik UI for WinForms NavigationView control. Use it to quickly locate how-to and troubleshooting guidance for configuration, customization, data binding, item population, styling, selection, and event handling.
Article: https://docs.telerik.com/devtools/winforms/ai-coding-assistant/mcp-server-as-nuget
Summary: This article shows you how to add and configure the MCP Server as a NuGet package in a Telerik UI for WinForms project to enable the AI Coding Assistant. You install the package, set up your LLM provider (OpenAI or Azure OpenAI), wire up the server and tools, and initialize it in your app so the assistant can access your workspace and files.
