An ArgumentException is raised when the DataGrid is unloaded in specific scenarios with the latest Q1 2024 release

The last columns are disappearing on dynamic content changed and are rendered as soon as the user taps on any item.  The issue occurs with devices/emulators with bigger screens when there are more columns shown -  tablets or devices in landscape mode.

filtering can no longer be applied as the "Reset" and "Filter" buttons are disappeared.

workaround use Xamarin.Forms v 4.8.0.1269

 If you open a datagrid's filter pop-up, navigate away from the page, then go back to the page, the filter pop-up will still be open.

If you attempt to close it, by way of the "X", the app will crash. In debug mode, a null reference error will occur. If navigating away from the grid with the filter closed, no crash will happen.

an issue when changing the orientation of the phone to landscape the items of the grid are rendered, then when go back to portrait the items that aren't rendered in the screen disappear.

Add the ability to specify a Template that should be shown when the DataGrid is empty.

Refer to the attached reproducible.

1. Run app and apply a filter: "Contains 0"

2. Notice #40 is in the correct location, between #30 and #50

3. Press the button on the bottom of the page to go BlankPage and then navigate back.

4. Observe #40 is now at the end of the rows even though the filter is clearly applied.

Look in MainPageViewModel.cs lines 42 to 49. When the navigation back occurs, this code is executed.  I can reproduce the problem with both Replace and Add+Remove operations.

public override void OnNavigatedTo(INavigationParameters parameters)
{
    base.OnNavigatedTo(parameters);

    if (!parameters.ContainsKey("from"))
    {
        var items = new ObservableCollection<MyModel>();
        for (var i = 1; i <= 100; i++)
            items.Add(new MyModel { Number = i.ToString() });
        Items = items;
    }
    else
    {
        var item = Items[39];

        // Bug Test #1 - using ObservableCollection Reset
        Items[39] = item;

        // Bug Test #2 - using ObservableCollection Remove & Add
        //Items.RemoveAt(39);
        //Items.Insert(39, item);
    }
}

Provide a way to associate a FilterDescriptor with a TemplatedColumn

While changing the orientation on mobile device to portrait or landscape, the columns' size is not calculated properly and the columns overlap on one another.

When the UserSortMode is set to single and it is sorted by a Template column that has DelegateSortDescriptor when we tap on another column the SortDirection of the Template is still visible.

If there a components which handles the Tap gesture (e.g. a button) is inside the TemplateCell, the DoubleTap gesture of the RadDataGrid throws NullReferenceException.

when the LoadOnDemand mode is set to Automatic and there are no more items for loading, the automatic load on demand is called

QSF DataGrid CRUD example
When editing the value inside the OrderDate column, the edited value is not presented in the OrderDate column. It keeps the old value

When starting an app that contians a RadDataGrid in the initial page, an exception is thrown because the telerikfont.ttf file is left unregistered.

Work-around:

Access anything from the TelerikFont class before the InitializeComponent of the page:

TelerikFont.GetUseEmbeddedFont(this);

Flicker can be observed when datagrid is manipulated/updated, or entering in edit mode. One example is tapping on a column header - when there is a column with a HeadetTemplate, the column header flickers. Other example is to double-tap a cell to go in edit mode. Also the behavior can be reproduced when DataGrid TemplateColumn is used.

When Filtering is applied to the RadDataGrid control and PropertyChanged is invoked by the visualized business object, the DataGrid rows are reordered inconsistently on tap

For Aggregates purpose or just for diplaying some others datas, footer for column in DataGrid it's needed feature.

 System.ObjectDisposedException:(Cannot access a disposed object) is thrown when switching tabs fast in RadTabView.

System.MissingFieldException: "Field not found" 'Xamarin.Forms.VisualElement.". is thrown when clicking the options button on each column's header. The issue occurs when updating to XF 3.5. 

Occasionally the DataGrid horizontal scrolling does not work properly after changing its ItemsSource.  Still, tapping on any item, make it possible to scroll again.
