I want to show a list of items with multi select on a click of a button. I figure our there are no dropdowns. Preferebly I would like to have a popup sort of component with list of items to select. Is this possible with PCL with out using native? 

Thankyou in advance

I use light and dark themes in my app(android + xamarin form). Calendar supported only light theme.

I try use :

      Calendar.SetStyleForCell = EvaluateCellStyle;

      ....
      private CalendarCellStyle EvaluateCellStyle(CalendarCell cell)

      { 

           if(DarkTheme)

               return this.Calendar.DarkStyle;

          else

              return null;

      }

But then my page is loaded for 5 seconds longer.
Maybe there is another way? 

I have a pull to refresh defined, and it renders and works properly on iOS, but when I run on Android, the ListView doesn't render at all. If I remove the "RefreshRequested" and "IsPullToRefreshEnabled", it starts rendering again. Any idea why?? I am using the newest release of UI for Xamarin.Forms. This is how I defined the list:

`<telerikDataControls:RadListView  x:Name="listView" ItemTapped="ListView_ItemTappedAsync" LoadOnDemandMode="Automatic" IsLoadOnDemandEnabled="True" LoadOnDemand="listView_LoadOnDemand" LoadOnDemandBufferItemsCount="5" RefreshRequested="listView_RefreshRequestedAsync" IsPullToRefreshEnabled="True">`

The color Boxes are stacked vertically. I want the to view them horizontaly. Is this possible?

Forms 2.3.4.270 / Xamarin iOS 11.0 / Xamarin.Android 7.4.5.1 

RadSlideView is veeery slow when recycling views.

Instead of shifting views and their bounding context left or right, all 3 views binding context are nullify and then reassigned.

Is should be like this:

ViewA             ViewB               ViewC
ViewModelA   ViewModelB    ViewModelC
                                *

// <== swipe this way

ViewC             ViewA               ViewB             
ViewModelD   ViewModelA    ViewModelB 
                                *

Then only one view's binding would change

Each time I added an element in the observable collection I had a delay of nearly 1 second...

It's really too bad since the implementation is otherwise quite nice and strong...

I have the following ListView set up.

The model that is bound to ListView is as follows.

The PhotoData property is ImageSource type and is obtained from base64 of the image as follows (this all happens before being bound to View).

And Employees (ListView's ItemsSource) is an ObservableCollection<Employee> property in ViewModel.

When I display a list of employees in a ListView everything works fine on Android. However, on iOS the employee photos flicker for 1 - 2 seconds when ListView is displayed. To be precise, it's not flickering, but rather photos change quickly before stabilizing. For example, if I have employees A, B and C in ListView, then on load I see that employee A has employee C's photo for split second, then it quickly changes to employee B's photo. Then it changes again, so that employee A has correct employee A's photo displayed. The similar thing happens for all employees in the list. (The order in which photos "flicker" may or may not be sequential - the order in which people are displayed in the list - because they change so quickly it's hard to tell. But eventually, when "flickering" stops, all employees have correct photos displayed.)

Please let me know what can be done to solve this.

Thanks

I want to add labels on top of (or next to) a Radial Gauge where the respective GaugeRangeBarIndicator is. 

How can I add labels next to the specific indicator section? Or is there a way that I can draw them manually?

I have a Xamarin Forms project where I am using calendar.

But I am having problems figuring out how to change the text color of the appointments on Android.

How do I do that?

I would like to do ScrollToItem in Xamarin Forms for my RadListView. I understand that the RadListView does not expose the method and I will need to create custom renderers on each platform.

Please provide an example of how to expose the method and how do I call that method from the View. Thanks.
