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
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.
If the user is clicking on a slider value that toggles the visibility of the green box to change (either show or hide), the slider thumb continues to follow the mouse cursor even after the drag should have ended. This continues until the user explicitly clicks somewhere on the slider again.
If the AutoComplete is nested inside a modal Popup and Unfocus() is called on SuggestionItemSelected or Completed, the cursor/focus stays within the AutoComplete.
The same does not happen (the AutoComplete is properly unfocused) when the control is placed in MainPage.
When adding a ComboBox in a page and navigating back from this page to another page, the app crashes.
PlatformView cannot be null here

Workaround:
If I wrap that command call in an ICommand then no issues.
Null reference exception occurs with maui 10.0.90
Just add the datagrid definition in xaml or code behind and exception occurs.

When navigating to DataGrid examples, xaml binding errors occur for ActualWidth and Header Text.
Still, the app runs as expected.
