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.

Barcode reader which can scan a barcode and input it in an entry.

I'd like it to work like the Telerik ListPicker control, which has the available setting IsLooping = false.

Do you have plans to develop controls for the UNO platform?

There are other companies that have already stated that they are working on it, for example,  

https://www.syncfusion.com/blogs/post/collaboration-syncfusion-uno-platform.aspx 

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. 

I would like to be able to render a street view in the RadMap.

For reference, this is StreetView as implemented by Google Maps Discover Street View and contribute your own imagery to Google Maps.

Provide a way to remove the appointment time display in Calendar AgendaView both on Android & iOS - on iOS there is a separate column for appointments' time that should be removed.

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();
    }
}

In the Map Control - Are background layers: Google / Bing / Open Street Map / WMS a possibility?

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.

I would like to make the dropdown appear to the right of the ComboBox instead of showing up below the ComboBox. 

Provide an API for changing the DropDown position. For example, the DropDown could be visualized above or under the input control - similar to AutoCompleteView control. 

Provide an option to programmatically reset the ordering of the columns in the DataGrid after reordering them using the Options-> more button

There isn't a command which can be used for resetting the column reorder.
