when loading same page without navigating to another page, there are some left instances of the DataGrid and the memory increase. 

Provide an event that occurs when the content in the DataGrid is drawn. 

When DataGrid is grouped and applying filtering, aggregates footer appears in the cells

If you use FooterContentTemplate to add elements into the footer that require mouse over/click events (eg a Button or a Label with a tooltip), it works fine as long as the datagrid has enough data to scroll. However, if you resize the grid bigger or remove items until you no longer need to scroll and you have empty space between the last row and the footer, then none of those mouse events work.

when setting a custom font to the column header style, the DataGrid crashes with null ref exception on WinUI.

When working in Windows with multiple monitors that have different display scales - dragging a window that contains a DataGrid with frozen columns would often lead to the frozen columns not getting rendered correctly. The frozen columns seem to not take into account the Dpi of the new monitor, but of the old one.

We're noticing issues related to grid load. We're observing the flickering of the data grid on launch.

In some cases, the grid would stay blank and won't recover until the window is resized (which would trigger repainting of the grid).

The behavior occurs with 11.0.0 version and above. With 10.1.0 no issues.

I want to select multiple rows by selecting one and then holding down the shift key and selecting more.

For example in WPF DataGrid there is an Extended multiple selection option: https://docs.telerik.com/devtools/wpf/controls/radgridview/selection/multiple-selection 

scrolling is not smooth (items jump up/down when scrolling)

Tested on Samsung S9+ and S10

When user resizes window with DataGrid inside - somehow grid content goes behind the header (see video)

Add text wrap formatting as the normal windows DataGrid control.

Hi Team,

I would like to be able to obtain a reference to a data item in the DataGrid when another UI element (outside of the DataGrid) is dragged and dropped onto it.

This feature request is to add the plumbing necessary to achieve that.

Thank you,

Tony

BorderColor style of the selected row does not apply on MacCatalyst and iOS.

.Net Maui Data Grid Property Aggregator Descriptor disappears when displaying columns in the same data grid which doesn't have aggregate property set

Hi Team,

Please refer to the following screenshot from the ControlsSamples project on Windows:

Notice the descender on the y character is pushing up the Delivery column header's Label container, but the Price text is flush with the bottom? This is causing misalignment between text in other column headers that do not have descenders.

You might not immediately notice this, for example in the Aggregates demo, only the first column has no descenders but the next two do. 

 

However, it's a more serious visual problem when every other column is vertically offset. Please consider adding a default Padding to account for descenders, or maybe change the VerticalOptions of the text container to be center aligned.

Thank you,

Matthew & Team

I have a DataGrid with ItemsSource bound to ObservableRangeCollection,
First I Clear() the existing items of the collection, then add new items, and raises a single CollectionChanged event with action = NotifyCollectionChangedAction.Reset.

the grid continues to show nothing.

This works with .NET MAUI CollectionView and ListView

Workaround: Add a delay after clearing the collection.

I have found that I am able to drag and drop columns across different datagrids, even when they are bound to completely different datasources. The function produces unexpected results- different columns end up getting get moved around on the grids.

IsCaseSensitive property doesn't work in the DataGrid control.

Workaround: Use Programmatic Filtering 

Example: https://github.com/telerik/maui-samples/tree/main/Samples/SdkBrowser/Examples/DataGridControl/FilteringCategory 

Disable the built in filtering UI and apply a custom UI with programmatic filtering.

I work on Maui Windows application and I use Telerik Maui Grid control. Current column filtering in this component is not bad but is not as user-friendly as Filter Row in Grid for Winforms. Can I create something like a Filter row in Grid for Winforms? Or have you a plan for adding it in the future to the Maui Grid component yourself?

Provide a user commands as RadListView that you could directly bind in the ViewModel.

Solution: 

Enhance the DataGridCommand class as a user command and in this way bind it to the defined commands inside ViewModel/ContentPage. - Sample project attached
