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

Null reference exception when using the AddSingleton approach in the shell app. 

Hi Team,

If the cell is frozen, the HitTestService.CellInfoFromPoint( ) method always returns null

Thank you,

Hey,

when binding to any collection of T with a nested property the DataGrid throws a NullReferenceExpection in Telerik.Maui.Controls.Compatibility.Common.Data.Fields.PropertyInfoFieldInfo.GetValue(object item) when the parent property is null, rendering nested propert< bindings kinda useless.

To mitigate this issue a Fallback-value option for each column (or at least catching the exception and returning null) would be nice.

When using CommitEdit command, the DataGridCellInfo Column and Value are null in the Execute method. The BeginEdit command contains the info for the Column and Value.

If a user changes an editable cell's value and then hit Tab, and the next cell to the right is not editable. Furthermore, the DataGrid enters into a state where no cells can be edited.

having shell project with two pages added in flyout items:

MainPage is with DataGrid, page2 with TabView.

On .NET 8 RC1/RC2 Switching back from page2 to MainPage results in a StackOverflowException from RadDataGrid.

With Shell navigation the first time the page with the DataGrid is navigated to, the DataGrid is properly displayed, if you return to the previous page with the Back button and navigate again to the DataGrid page, the control is not visualized on Android.

There doesn't seem to be an attribute within DataGridColumnHeaderStyle that lets me set the height of the header.

The reason I am looking for this feature is because I want the header to change height to fit the font size

There is a memory leak in DataGrid on Windows - when the DataGrid control is on the page, the page does not dispose when GC runs.

Can we get the ability to turn off the dynamic sorting of the DataGrid? Currently, if we sort on a column for a property that's updating often, every update ends up re-evaluating the sort, so we end up with rows jumping up and down, which can get very distracting when rows that are constantly moving around.

I would like to use a mouse to drag a row to a new spot in row order.

Found this info for WinForms, but not finding anything for MAUI RadDataGrid

Currently if the DataGrid columns have Fixed or Auto size and their overall width is less than the DataGrid width, the rows are not extended to the DataGrid width - provide a way for the rows to take the whole space.

When the DataGrid is bound to an ObservableCollection and its Clear() method is called in order to reset the source and add new items, the scroll position is not reset to the top.
