Telerik UI for .NET MAUI

Unlocking the Potential of Row Details in DataGrid

Imagine a situation where you need to display a list of products in your application. A typical row could include basic information such as the order ID, date, shipped date and estimated date. However, what if you want to present additional details like shipping address, customer or assignee information without cluttering your grid?

This is where the Telerik UI for .NET MAUI Row Details feature shines. It allows you to keep your grid clean and straightforward while providing an option to access more detailed information on demand. It enhances the user experience by making your application interface more interactive and less cluttered.

Row Details

For more information on getting started with this feature of the DataGrid, visit the Telerik UI for .NET MAUI documentation.

DataGrid: New Header Cell Hover Effect

The hover effect of the DataGrid’s Header Cell is a feature that changes the appearance of a column header cell in the DataGrid when the mouse pointer hovers over it. This interactive visual cue allows users to understand that they can interact with the header cell, offering potential actions like sorting or filtering data, or indicating that the column can be repositioned by dragging.

hovering on header cell turns the background from white to light gray, showing it is clickable

Moreover, you can customize header cells to better represent the data they’re associated with, making your grid more intuitive and visually appealing.

Whether you want to include an icon with the header text, change the sorted state of the header, or add additional visual elements, the HeaderContentTemplate provides the flexibility to do it all.

Here is a simple example:

Header cells have icons for filtering and sorting

Telerik UI for WinForms

The R2 2023 SP1 release of Telerik UI for WinForms comes with a modern legend feature to the brand-new Heat Map control, redesigned examples in demo application, fresh new look of Visual Style Builder and various other improvements.

Heat Map Legend

The legend is a great addition to the freshly released Heat Map Control in the R2 2023 release. Technically speaking, the legend relates the color spectrum of the heat map cells to their corresponding numeric values. It is a feature that allows the end user to easily interpret and operate through the control’s color palette.

The legend is fully customizable—by default, the control automatically creates items based on the current definition and colorizer, and in addition to this you can also modify them or create your custom legend items.

See the detailed list of the What’s New items to learn more:

Telerik Reporting & Telerik Report Server

Radial Gauge was released in R2 2023 to enable displaying the important business KPIs in a visual manner. We received feedback that its public API may be improved, and we listened. Now all the scalar properties of the model represent units relative to the item’s size, so its content resizes gradually when the item gets resized.

More importantly, we also introduce a Linear gauge item so that these KPIs can be represented in any possible visual manner.

screenreader preview

We continue to build on our PDF accessibility functionality introducing various improvements so that assistive technologies work even better. Check out the full list in the release notes.

Again based on user feedback, we exposed the evaluated report parameters in the client APIs of Blazor, React, Angular and HTML5 report viewers, which allows for implementing more custom behavior scenarios.
