Release R1 2021 SP1
When you edit a value of a certain item and you tap outside of the DataGrid, so it loses the focus, the edited value is not committed and the DataGrid stays in invalid edit state.

Currently, hiding the 'more' button in the of the DataGrid filter Options panel is not possible.

This is a feature request to add such an option to the DataGrid column styling options (potentially as a property of the HeaderStyle).

In case RadDataGrid is populated with large amount of items (~5000 items with 10 columns), scrolling horizontally to the right most side and reloading the data ( updating the ItemsSource) results in a non-responsive app.

Release 2020.3.1207 (R3 2020 minor release)

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.

 In Tab1 I have a DataGrid and in Tab2  I have also a DataGrid with data.

When you click on the change data button the data will change in Tab1 and Tab2. But when for example Tab2 is visible then the data in Tab1 is not updated when you go to that tab. When you resize the app then the data becomes visible.

My mobile app requires that my data grid have frozen columns on the left that do NOT scroll horizontally.  This is useful when the first column might be an ID column or a Date column that the user always needs to see when scrolling through the other data columns.

If you use a TrueType font for the DataGrid column's OptionsButtonFontFamily, it is not respected and falls back to a default OS font.

Workaround

The only workaround at this time is to create a custom column HeaderTemplate with a custom options button and hide the default options button.

<dataGrid:RadDataGrid x:Name="dataGrid" ...>
    <dataGrid:RadDataGrid.Columns>
        <dataGrid:DataGridTextColumn x:Name="productNameColumn" PropertyName="ProductName">
            <dataGrid:DataGridTextColumn.HeaderContentTemplate>
                <DataTemplate>
                    <Grid>
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition/>
                            <ColumnDefinition/>
                        </Grid.ColumnDefinitions>

                        <Label Text="Name" TextColor="Black"/>

                        <Label FontFamily="MyCustomFont.ttf#MyCustomFont"
                                    Text="&#xE717;"
                                    TextColor="Orange" HorizontalOptions="End" HorizontalTextAlignment="End" Grid.Column="1">
                            <Label.GestureRecognizers>
                                <TapGestureRecognizer Tapped="TapGestureRecognizer_Tapped"/>
                            </Label.GestureRecognizers>
                        </Label>
                    </Grid>
                </DataTemplate>
            </dataGrid:DataGridTextColumn.HeaderContentTemplate>
            <dataGrid:DataGridTextColumn.HeaderStyle>
                <dataGrid:DataGridColumnHeaderStyle OptionsButtonFontSize="0" FilterIndicatorFontSize="0"/>
            </dataGrid:DataGridTextColumn.HeaderStyle>
        </dataGrid:DataGridTextColumn>
    </dataGrid:RadDataGrid.Columns>
</dataGrid:RadDataGrid>

In the code-behind, we use reflection to access the column's command context and invoke the options menu via DataGrid command service.

public partial class YourPage : ContentPage
{
    private readonly MethodInfo generateOptionsTapContextMethodInfo;

    public YourPage()
    {
        InitializeComponent();

        this.generateOptionsTapContextMethodInfo = this.dataGrid.GetType().GetMethod(
            "GenerateFilteringCommandContext", 
            BindingFlags.NonPublic | BindingFlags.Instance);
    }

    private void TapGestureRecognizer_Tapped(object sender, EventArgs e)
    {
        if (this.generateOptionsTapContextMethodInfo != null)
        {
            // Get a reference to the column, this is needed to invoke a command
            var context = this.generateOptionsTapContextMethodInfo.Invoke(
                this.dataGrid, 
                new object[] { this.productNameColumn });

            // Invoke the command service that opens the options button
            this.dataGrid.CommandService.ExecuteDefaultCommand(
                Telerik.XamarinForms.DataGrid.Commands.DataGridCommandId.OptionsTap, 
                context);
        }
    }
}

The horizontal scrollviewer is not visualized initially when the column header text is longer than the columns' text. Still, tapping on any item makes it possible to scroll.

Hi,

The DataGrid does support or response to Custom Font set Using the ExportFont Attribute. But when a contentTemplate is used and a label control is place in it. The font shows on the label but not on the Header or Content of the Grid.

If you open the filtering UI of a TextColumn, start typing into the "Enter filter criteria" field and press "Reset" or "Filter", the filtering UI is closed, still, the soft keyboard is not hidden.

To reproduce:

Step 1 - File > New > LoadOnDemandCollection Demo

Follow the LoadOnDemandCollection documentation https://docs.telerik.com/devtools/xamarin/controls/datagrid/load_on_demand#loadondemandcollection

Step 2 - Deploy to UWP

=> Observe the DataGrid will be stuck in busy state after the initial set of items load

Release R1 2020 SP1
 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.
