When applying multi-level grouping, then change the items group keys, the new groups are added but the old ones are still visible in the list view, and from child group they become parent group. 

 

Workaround:

clear the group descriptors before changing the items and then re-add the group descriptors again

Provide a new view similar to Day/MultiDay View with horizontal timeline - in this way it would be easier to accommodate more appointments for a certain timeslot. 

This timeline would be scrollable vertically to fit as many calendar events as needed, and horizontally to fit all time frames.

Hi Team,

Please consider adding Open/Closed event for the comboBox's popup. The validation for this is I need to perform validation if a user closes the popup without making a selection.

SelectionChanged doesn't work here, because user never selected anything. Focus events are very finnicky because of the platform differences and input modalities.

The only sane options is to add an official PopupClosed event (and you don't even need custom EventArgs).

Thank you!

Bobby

 

Workaround

For now, I am using reflection+ nonPublic|Instance BindingFields to get a reference to the private RadPopup field of the RadComboBox. With that reference, I am subscribing to PropertyChanged and watching for value changes  of the IsOpen property. 

It goes without saying, this is a very resource intensive and unofficial approach.

public partial class MainPage : ContentPage
{
    private RadPopup internalPopup;

    public MainPage()
    {
        InitializeComponent();
    }

    protected override void OnAppearing()
    {
        base.OnAppearing();

        var popup = typeof(RadComboBox).GetField("popup", BindingFlags.NonPublic | BindingFlags.Instance)?.GetValue(ComboBox1);

        if (popup is RadPopup p1)
        {
            internalPopup = p1;
            internalPopup.PropertyChanged += InternalPopup_PropertyChanged;
        }
    }

    private void InternalPopup_PropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e)
    {
        if (e.PropertyName != nameof(RadPopup.IsOpen))
            return;
        
        if (internalPopup.IsOpen)
        {
            // Popup was opened
        }
        else
        {
            // Popup was closed
        }
    }

    protected override void OnDisappearing()
    {
        if (internalPopup != null)
            internalPopup.PropertyChanged -= InternalPopup_PropertyChanged;

        base.OnDisappearing();
    }
}

The image editor is a great start, but missing a critical feature - image drawing / annotation. The ability to draw lines, shapes or text onto an image. Should allow this to be done when pinch / zoom is in progress. Items drawn should be amendable until saved. Opportunity to retrieve the annotation only data separately to the image so you can preserve the original.

DataBindingComplete event of the DataGrid should be fired when the associated data (ItemsSource) has been successfully bound to the control or any data operation like Group, Sort or Filter is applied.  Currently the event handler is not called as expected.

RdBusyIndicator BusyContent data binding does not work. If a string constant is assigned to the     

 

     <telerik:RadBusyIndicator
                HorizontalOptions="FillAndExpand"
                VerticalOptions="FillAndExpand"
                IsBusy="{Binding IsBusy}"
                IsVisible="{Binding IsBusy}"
                AnimationContentHeightRequest="60"
                AnimationContentWidthRequest="60"
                AnimationType="Animation3"
                AnimationContentColor="{DynamicResource BrandPrimaryColor}">
                <telerik:RadBusyIndicator.BusyContent>
                    <Label Text="{Binding BusyContent}" HorizontalOptions="Center"/>
                </telerik:RadBusyIndicator.BusyContent>
      </telerik:RadBusyIndicator>

 

RdBusyIndicator BusyContent data binding does not work for the above Label inside the "telerik:RadBusyIndicator.BusyContent". If a string constant is assigned to the Text(for example "Loading..."), then it works perfectly.

The view model 100% has the property "BusyContent" with a value. By the way, the IsBusy and IsVisible data binding work fine.

Most PDF Viewers come with the ability to print, email, text etc the PDF that is loaded.  For example, in the default iOS PDF viewer there is a "share" icon.  When the "share" icon is tapped, multiple options and apps come up that allow users to "print", "message/text", "email" the PDF.  It would be a great feature to have in the Xamarin UI PDF Viewer.  It could just be part of the PDFViewer Toolbar options.

On Android if the text is longer than the input field and it is set from OnAppearing method, RadEntry displays the ending of the text instead of the beginning.

Also, the issue can be reproduced

when the Entry text is set in code behind, for example on button click:
private void Button_Clicked(object sender, System.EventArgs e)
        {
            this.radEntry.Text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. ";
        }



inside the AutoCompleteView control when select an item from the suggestion items list.

After scrolling down enough times where all of the data is loaded, if I try to scroll a bit more, things go a bit crazy.  A loading icon flickers on and off over the grid; the data in the grid flickers away and then back; and the entire UI essentially gets stuck in this situation.
