Hi Team,

I would like to be able to have client-side filtering/sorting/grouping capabilities for large backend datasets that cannot be entirely loaded on the client.

As it stands now, the DataGrid (and other data components) can only operate on the data that is has in the local DataView. This means that I need to build a custom filtering solution that prefilters/presorts the backend data before paging and loading it into the DataGrid.

To accomplish the "full view", we need a data layer that understands both the UI as well as the backend. The Telerik UI for WPF product has an excellent solution for this, known as the WPF EntityFrameworkCoreDataSource - Overview - Telerik UI for WPF and the WPF DataServiceDataSource - Overview - Telerik UI for WPF.

If such a feature can be added to Telerik UI for MAUI, it would be an excellent bonus for the component suite in data heavy applications.

Thank you,

Peter

 

When RadDataGrid uses LoadOnDemand with a plain ObservableCollection<T> as its ItemsSource, there is no supported API for the application to indicate that no further items are available.

As a result, the grid can continue raising LoadOnDemand requests after the data source has returned all available items. Applications must currently maintain pagination state and use a custom LoadMoreData command or other workarounds to prevent additional requests.

Provide a supported option that allows applications to stop load-on-demand once no further data is available. The grid should resume requesting items when the relevant data/query state changes.

On Android, the application crashes during login/navigation after the Telerik license warning overlay has been displayed. A subsequent overlay refresh deinitializes MAUI’s `WindowOverlay`, which attempts to remove its graphics view from a previously disposed native `CoordinatorLayout`.

The old Chart object supported LabelFitMode but the new Charts does not have this.  Provide a method to rotate the labels on an Axis.

The DataGrid is blank in when using AOT compilator

the following scenario: 2 property aggregate descriptors that use different properties than the property bound to the column and when editing the column, one of the property in the footer text does not update the value in the UI. 

option to have gradient and color change for the new charts

for example point markers on line, area, scatter line and spline series

provide tooltip/trackball on hover data point and when pressing the point- check the attached image. 

provide tooltip on hover the pie donut data point, also on selection to display the tooltip - image is attached

Provide cross hair feature similar to kendo -> https://www.telerik.com/kendo-jquery-ui/documentation/api/javascript/dataviz/ui/chart/configuration/axisdefaults.crosshair  

the requirement is exactly what you have on the kendo chart crosshair where the horizontal line follows the mouse while the vertical line locks to the nearest datapoint. 

Provide an option to display a chart title and align it to top left, right and center and bottom left, right and center

Provide an option to display a chart legend for pie and cartesian series. Also provide an option to change the legend position to be left, top, bottom, right position to the chart

now when navigating to the control using the tab key, the first segment gets focused, so I want first the entire control to get focused, then each segment. So provide an option to focus the entire control first using the tab key

provide support for : narrator and voice over
and the screen reader should  announcing:

• Announcement of the currently focused segment during keyboard navigation.
• Announcement of selection changes.

I'd appreciate proper selector for this. I think that's a good addition for DataGrid customization having a style selector for the mouse hover based on the cell value

having a scenario when setting a definitive height to the popup and trying to display the footer buttons end vertically aligned, this does not work. 

I want to be able to drag my mouse over cells to select them.

Provide an option to drag a cell content and drop it to another cell for both default and skia render modes

Makes this feature also available for skia cell renderer

This is a request to have a Markdown Viewer added to Telerik UI for Maui's portfolio. Something similar to these:

• https://shinylib.net/controls/markdown/
• https://www.syncfusion.com/blogs/post/markdown-viewer-dotnet-maui
• https://github.com/0xc3u/Indiko.Maui.Controls.Markdown

We would only need the ability to view markdown. Not edit it.

Thank you,

Teddy
