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

 

Automatically change the background and text color depending on the applied Telerik theme.

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.

Provide an option to raise PropertyChanged event without a PropertyName that you just update everything related to that object's row, including all its cells and aggregates

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

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

you have a slider and range slider.

add circular slider control. 

Enable keyboard navigation for the control.

I see we can set the SuggestionView's height. And we can set a combo box's DropDownWidth. Can we also get a SuggestionViewWidth property on RadAutoComplete?

Similar to the SegmentedControl https://www.telerik.com/maui-ui/documentation/controls/segmentedcontrol/selection#selection-modes , provide a single deselect SelectionMode option for the CollectionView. 

Allow for up/down arrows to step up/down the time element with the keyboard cursor. For example, if I have my keyboard cursor on the hours of a time, then pressing up would increase the hour by 1.

Keyboard support for the dropdown... Space to open, tab and/or arrows to cycle through and change the date/time.

 

I want to have a single deselect built-in using keyboard key. 
There is a feature request for single deselect selection mode here: https://feedback.telerik.com/maui/1715480-collectionview-provide-a-single-deselect-option-when-tapping-the-selected-item-again-to-be-deselected 

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.
