Can we have an option to allow users to select the default placeholder item to deselect the selected item and revert the list picker to a placeholder? (eg. when the list picker popup is opened, show a placeholder on top of the items.  If that item is selected, the selected item of the list picker is cleared, similar to how there's a placeholder option for dropdown lists in the web).

We should consider splitting the Telerik.Xamarin.iOS.dll into separate DLLs so that the customers can reference only the controls they need.

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.

When an item in the ItemsSource of a ListView is null, a NullReferenceException will be raised on Android when the items source is loaded to the list view.  Even if a DataTemplateSelector is applied to display a different datatemplate for null items, the app would still crash.

I attached a sample program that demonstrates the issue.  On iOS the app runs fine, but on Android the app crash at launch with a NullReferenceException.

Thanks,
Kori

Activating the ItemHold event of an item in a list view requires holding down an item for a while.  On a physical/virtual Android device and a virtual iOS device, this can be done by holding down the mouse/finger lightly on an item for a short period of time.  However, on a physical iOS device (I am using a physical iPhone 6s to test this), holding down the item lightly with my finger won't activate the ItemHold event, and I have to hold the item really hard on the screen in order to activate it (similar to using 3D Touch / Force Touch, and I cannot reliably activate the ItemHold event possibly because my force is sometimes not hard enough).  I noticed this behaviour on the physical iOS device since the ItemHold event got implemented in early 2018.

I created a simple application to demonstrate the issue.  The app displays an alert when the user taps/holds an item in the list view.  On a physical iOS device, holding down an item in the list view requires the user to press the item very hard on the screen.

Thanks,
Kori

Users need to restrict suggestion of already selected tokens. 

In other words when users create a token, that particular item should not be suggested when typing new tokens anymore.

I'm particularly wanting the "Assistive labels" features, which comes from Material design (click in the textbox, and the watermark becomes a floating label).  Like this:

When RadListView is in grid mode (SpanCount > 0), there is no spatial navigation with the keyboard.

Up and down arrows move the focused item, left and right arrows don't. (Also: it doesn't seem to be possible to style the focused item…)

Crude drawing:

 

Only the first column has keyboard navigation, up and down. It's invisible, though; internally, an item is focused and will execute ItemTap when pressing the return key, or will select the item when pressing the spacebar. That part is fine.

 

After clicking/tapping an item in any column after the first one and then pressing the down arrow, for example, we get this:

Pink is where we clicked/tapped, cyan is what's internally focused after pressing the down arrow. 

Please note again that focus != selection. 

 

Expected behavior:

  • Implementation/exposure of FocusedItemStyle
  • Left and right keyboard arrows should move focus spatially inside the grid; if RadListView is in 1-column (list) mode, Left == Up, Right == Down

 

Further suggestions:

  • Implementation/exposure of HoverItemStyle, for when the mouse pointer is over an item cell
  • (changed) ScrollItemIntoView(object item, boolean focusItemAfterScroll, boolean selectItemAfterScroll)
  • (new) FocusItem(object item) 
  • (new) SelectItem(object item)

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);
        }
    }
}

When you place a Label with TextType set to "Html" inside ListView TemplatedCell, the ListVIew renders only the items currently in the viewport - if you scroll down, the listview is empty.

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.
