Release 2019.2.708 (R2 2019 minor release)
When there is custom template applied that hosts multiple rows of UI components with total height greater than 44, the template is not measured correctly, leading to wrong visualization.

Using the RadPieChart and PieSeries (UI for Xamarin v2019.2.802.1 from NuGet), I can currently set the LabelBinding (or LabelFormat or LabelFormatter) to adjust the strings displayed in the labels on the slices of the pie chart, but unlike other chart controls, I currently have no way to modify the styling of those labels like I can in every other chart control I've used from Telerik UI for Xamarin.

It seems to me that it would be best to have more properties on the PieSeries class, like LabelFontSize, LabelFontAttributes, LabelFontFamily, LabelTextColor, and LabelMargin (Label prefix to distinguish from LegendTitleBinding could be kept or discarded as desired on some of these names).

LabelMargin would be particularly helpful to eliminate the UWP situation wherein currently all pie slice labels overlap with the outer lighter ring of the pie chart (see image from UWP).  The others just seem needed to maintain a consistent appearance of charts within an app - if all my chart labels are dark blue and a different font size and style except for the not-style-able black labels in pie charts, that makes pie charts hard to incorporate without looking bad or forcing styling elsewhere to match the pie charts' fixed values.

On UWP, the RadCalendar's DisplayDate isn't updated when the month's view changes (via user selecting the up/down arrows in the header).

When display is on high resolution screen (MS surface book screen 3000*2000 with 200% scale) the DataGrid is not resized correctly.  See attachments.

Hi,

I have been using Telerik controls for the last 4 years in WPF.  One of the controls widely used is the RadScheduleView in which I manage customer appointments in hair dresser salons.  Recently I tried to implement the same functionality on Mobile Apps using Xamarin.

 

Some of the appointments generated by users contain overlapping times since they are serviced by different employees.  This functionality in WPF is managed perfectly using RadScheduleView.  Now I am using the same data by downloading it into a MobileApp (for now Android App) and reproducing similar appointments but on RadCalendar.  Every time an appointment have overlaps, the way system is recreating it on the calendar is misleading and sometimes appointments are also hidden.

 

The following is a Code snippet that also produce the same results.

Steps to reproduce:

 1. Appointment View module that inherits from Telerik.XamarinForms.Input.Appointment and add additional properties to manage appointments:


 public class AppointmentViewModel : Telerik.XamarinForms.Input.Appointment
    {
        public Int32 PK { get; set; } = -1;
        public String DisplayStartTime
        {
            get
            {
                return StartDate.ToString("HH:mm");
            }
        }
        public String DisplayEndTime
        {
            get
            {
                return EndDate.ToString("HH:mm");
            }
        }
        public double AppointmentDate
        {
            get
            {
                return StartDate.Date.ToOADate();
            }
        }

        public string AppointmentDisplayDate
        {
            get
            {
                return StartDate.Date.ToString("ddd dd MMM");
            }
        }
    }

Note:  To render appointments, I am still using default properties of the class  Telerik.XamarinForms.Input.Appointment,  see point 3.

 

 2. Create Page (XAML) with calendar and a refresh button:


<?xml version="1.0" encoding="utf-8" ?>

3. Code Behind the Refresh Button :


       private void BtnRefresh_Clicked(object sender, EventArgs e)
        {

            cntAppoints.DisplayDate = DateTime.Parse("11/05/2019");

            ObservableCollection<AppointmentViewModel> apps = new ObservableCollection<AppointmentViewModel>() {

            //expFilters.IsExpanded = false;
        }


 

4. After running the above code, the following issues are encountered when appointments are generated on the calendar (screens taken from original application):

  •  Customer_8.jpg - Appointment for Customer 8 is overlapping appointment with customer 7 when on calendar there is enough space in the other columns;
  •  Customer_14.jpg - Appointment for Customer 14 is overlapping appointment with customer 12.  Appointment for Customer 13 is hidden under Customer 14;
  • Customers_26_27_28.jpg - Appointments for Customers 26,27,28 are overlapping with appointment for customer 24 when on calendar their is ample space were to generate these appoints.
  • Customer_32.jpg - This is the worst scenario.   Appointments for Customer 32 and 33 are sharing the same time slot.  This appointments overlapping and users can only view appointment 33.

 

 

Can you please give me an indication what I am doing wrong in my code or how can avoid such cases.  The scenarios indicated above are misleading to the final users.  I notised that such tickets for similar issues where raised since 2017 but never finally answered.

Using the code code below, the RadBusyIndicator will animate the first time you toggle IsBusy.

However, any subsequent changes to IsBusy will show the AnimationType's graphic, but without animation.

<telerikBusyIndicator:RadBusyIndicator x:Name="radBusyIndicator"
                                               AnimationType="Animation4"
                                               IsBusy="{Binding IsBusy}"
                                               IsVisible="{Binding IsBusy}"
                                               Grid.RowSpan="3" />

consider adding a "max height" and "max width" option so that the file sizes are manageable. So in that scenario if we set the max height to 450 then we shouldn't see anything larger than 800x450 in the result.

Hi there,

 

We're struggeling with the radentry control. For login purposes we use one for the password and one for the email. When we set IsPassword=true this does show dots instead of words, but some basic stuff isn't working.

1) The normal entry with IsPassword=true does also hide the suggestion tab that is above the keyboard. We also tried hiding this with other settings but to no result. This control should also hide suggestions since it is a password and we don't want to cache this in any way.

2) When we replace the radentry password field with a xamarin entry password field (so set IsPassword=true on both) then we also get the password fill option. In this case Samsung keypass. I imagine if people are using autofillers such as samsung, google, or something else, that this should also work since i'm stating the field is a password field.

Tested on android with multiple devices.

Thanks in advance!

Expose an IsEnabled property for editors that can be toggled after DataForm is rendered.

Currently, only Data Annotations can determine whether or not a property's editor is read-only. If a specific editor's read only state needs to be changed dynamically (e.g. due to a selection in another editor), you would need to completely reload the DataForm.

Add public-facing methods to re-call DataSourceProvider GetSourceFor methods. This would allow for refreshing the datasource.

Alternatively, add support for ObservableCollection to be used for DataSources so that the pickers reflect any changes to the underlying data source.

As an effect of this, characters, which are not contained in the StandardEncoding names, e.g. umlauts, are measured with incorrect glyph widths. This leads to incorrect glyph positioning in RadPdfViewer.

It would be a good to have function to be able to swipe on the header and also to be able to swipe on the content area to go to next tab.

Hi,

As the header suggests, Swipe No Longer Works When Offset And Threshold Are Equal, the swipe closes on finger release. This started happening in the latest release, 2019.2.619.1, previously this worked without issue.

This can be replicated in the SDKBrowser by setting the following in Cell Swipe - Interactive Content example:

SwipeOffset="70, 0, 0, 0"
SwipeThreshold="70"

I have only tested this on Android. 

Regards

Anthony

Currently, the RadSegmentedControl only has support for SelectionChanged. I need an event that will fire if the user selects the same item again. 

Note that GestureRecognizers don't work (i.e. TapGestureRecognizer), so this will need to be a Telerik-implemented event.
