In this blog post, we'll review the major features we expect to ship in our mid-year release (v26.1 - June 2026). These features apply to both DevExtreme JavaScript components (Angular, React, Vue, jQuery) and DevExtreme-based ASP.NET MVC/Core controls. To help us fine tune our release plans, please respond to the survey questions embedded within this post to share feedback. Alternatively, submit a support ticket via the DevExpress Support Center. We will be happy to follow up.

Roadmap Updates
This roadmap will be regularly updated to reflect development progress. As we get closer to the release, we expect to add more items and modify the status of planned features. Look for the following labels next to each feature:
Planned - Feature is scheduled but not yet in development.
In Development - Under active development.
Released in Beta v26.1 - Will be available in our v26.1 beta release.
Released in v26.1 - Fully implemented and available in v26.1.
DataGrid & TreeList — AI Assistant
All Platforms
Planned
With our v26.1 release, we will extend the AI-powered capabilities of both the DevExtreme DataGrid and TreeList. We plan to introduce a DevExtreme Chat-based AI assistant that will allow you to use natural language to interact with DataGrid/TreeList. The DataGrid/TreeList AI assistant will be able to complete the following actions:
- Sort, filter, search, and group data.
- Resize, reorder, fix/unfix, and show/hide columns.
- Change pagination settings.
In our last release (v25.2), we introduced a standalone Speech To Text component. By incorporating this component into our Chat component (planned for 26.1), you will be able to add Speech to Text to your next DevExtreme-powered AI Assistant as well. This will eliminate the need for manual configuration and improve accessibility when working with DataGrid/TreeList (by offering an additional interface when interacting with UI elements).
This feature is particularly well suited for the following usage scenarios:
- Large Datasets: Use the power of AI to browse large data sets. Apply complex filter values with natural language.
- Complex Grid Configurations: Allow users to specify complex display preferences quickly.
- Accessibility-first Applications: Allow users to interact with your application in a manner that is most appropriate for each specific situation: while at their desk, or on the go (when their hands are busy and they require voice commands to interact with your app).
- Replicable Configurations: Apply the same prompt to recreate complex grid configurations across sessions. Reduce time spent on tedious layout adjustments.
DataGrid & TreeList — Persistent Validation Messages in Editors
All Platforms
Planned
We expect to introduce new APIs that will allow validation messages to remain visible even when data editors lose focus (similar to the validationMessageMode='always' in components such as our TextBox). These APIs will apply to all available editing modes.
Chat Enhancements
Speech To Text
All Platforms
Planned
We expect to integrate our new SpeechToText component into our Chat component's input area for faster, hands-free communication.
Message Streaming
All Platforms
Planned
We expect to add support for message streaming within DevExtreme Chat. The Chat component will be able display responses progressively as data arrives rather than after the request is fully completed. This feature will improve perceived performance and the overall user experience for DevExtreme-powered AI assistants, chatbots, and long-running operations, making conversations feel more dynamic and responsive.
Tool Call Visualization
All Platforms
Planned
We will introduce the ability to display AI tool/function calls in the message body. Such tools/functions can be declared locally within the app or available via MCP servers.
This visualization will increase clarity and transparency. Chat users will be able to see which tools were used, their order, and parameters alongside AI response.
Scheduler Enhancements
Appointment Snap Modes
All Platforms
Planned
DevExtreme Scheduler will include a new appointment snap mechanism. The following modes will be available:
- always - an appointment always stretches to cell borders.
- auto - an appointment is stretched to cell border only if the distance from the cell border to the edge of an appointment is less than half of the cell width.
- never - appointments are proportional to their duration.
Handle Appointment Time Overlapping
All Platforms
Planned
Managing appointment overlapping will be easier with our next release. We will add public APIs to obtain an array of appointments for a specific range. You will be able to implement the following scenarios using these APIs:
- Prevent Time Conflicts: Notify users about a scheduling conflict. Restrict adding, editing, or moving appointments if the selected time slot is already occupied.
- Suggest Available Time Slots: Automatically suggest the nearest available time when a selected slot is unavailable.
- Handle Recurring Appointment Conflicts: Detect and manage conflicts for individual occurrences within recurring appointments.
- Execute Overlap Rules: Apply different overlap rules depending on the appointment category.
- Enforce Buffer Time Between Appointments: Require a configurable gap before and after appointments to avoid tight scheduling.
Hide Specific Days
All Platforms
Planned
You will be able to hide specific days in week and month views, for example, weekends or custom day sets.
UI/UX and API Enhancements
TreeView — Prevent Selection for Disabled Nodes
All Platforms
Planned
With v26.1, you will be able to prevent recursive selection state changes for disabled TreeView nodes.
We will also add the ability to expand/collapse disabled parent nodes.
Application-Wide Date Formats
All Platforms
Planned
We will introduce new APIs designed to specify a single date format for all DevExtreme components within your application.
Globalization — Separate Text and Date/Number Locales
All Platforms
Planned
In v26.1, you will be able to specify different locales for application text values and dates/numbers. You will be able to change languages without affecting date/number formatting and vice-versa.
Accessibility
All Platforms
Planned
We expect to improve accessibility for the following DevExtreme UI components:
We will also improve color schema in our Material themes to comply with accessibility contrast requirements.
Additionally, in v26.1, we expect to introduce screen reader support for Rich Text Editor for ASP.NET Core.
Our long-term goal is to address all limitations identified in our DevExtreme Accessibility Conformance Reports (ACRs).
Migration Away from CommonJS
All Platforms
Planned
As part of our ongoing modernization efforts, we will eliminate use of CommonJS. We plan to remove all CommonJS modules and imports in DevExtreme packages and source code. This change will optimize DevExtreme package size.
Please share your thoughts on this transition in the survey below. Your feedback will help us identify potential migration challenges and make the transition as smooth as possible.
Angular 22
Angular
Planned
The release of Angular 22 is planned for May 2026. As part of our commitment to same-day support for new versions, DevExtreme v26.1 will offer full compatibility once Angular 22 is available.
According to Angular's official support schedule, Angular 19 will reach end-of-support in May 2026. With v26.1, we will also update our minimum supported Angular version to 20.
ASP.NET Core
UI Template Kit Update
ASP.NET Core
Planned
DevExpress UI Template Kit includes application templates for ASP.NET Core. The templates help you start new projects quickly (templates address predefined application usage scenarios, which you can tailor to meet specific business requirements).
In our upcoming v26.1 release, ASP.NET Core application templates will be more flexible, with a built-in navigation area and a set of pre-configured views (with controls such as DataGrid).
