Hi and thanks in advance.

I want to use the autocomplete in Append mode only and this is the setup of the control:

ItemsSource="{Binding References}"                                   
TextSearchPath="Name" SearchThreshold="3"
ShowSuggestionView="False" SuggestMode="Append"     
DisplayMode="Plain" CompletionMode="StartsWith"
NoResultsMessage="No matching references..."     
IsClearButtonVisible="True"
SuggestionItemTextColor="{DynamicResource ColorPrimary}"
SuggestionItemSelected="VisitorReferenceAutocomplete_OnSuggestionItemSelected"
FilteredItemsChanged="VisitorReferenceAutocomplete_OnFilteredItemsChanged"
Style="{StaticResource AutocompleteBaseStyle}"

After 3 digits a match is found and the FilteredItemsChanged event is triggered correctly but the cursor inside the textbox goes back to the start position and the name inside the textbox is not autocompleted at all. Moreover...what is the behavior of the clear button? Sometimes it works e and sometimes not, in any case how I can understand that the selection is now empty (FilteredItemsChanged  again?).

The Xamarin.Forms version is the last 3.1.0.697729 and the solution targets only android platform (8.1 Oreo, api 27)

Hi everyone,

A while ago we developed an app for one of our customers, using Telerik UI for Xamarin Forms. The app is used for showing financial data.
Recently, our client has made changes to the specifications and design of the used Telerik components.

At this moment my most experienced Xamarin developer is not available, but I need information if the design and specifications made are possible or not in Telerik UI for Xamarin Forms.
Can you provide me with information? As soon as I know what is or is not possible, I can pass this on to my client, after which my developer will be able to realize this as soon as he is present again.
Underlying information: The data from the charts and widgets is fed from an underlying database and can be configured yourself (the customer can decide for himself which financial data is shown where and hat is shown (line chart, piechart, bar chart or gauge))
See the added images

Gauge
In the current app of our customer, we did not use gauges. So far, we do not have any experience with it yet. I read on the Telerik website that a lot can be customized, but can not find clear information about how far this is possible.
Is this design of the gauge within Telerik possible? Think of the shape, whether it is possible to give the color / color gradient per gauge, the needle

Barchart
Is it possible to give a color gradient?

Linechart
In the desktop version of the application we use Telerik UI for ASP.NET MVC. Here, bullets are shown per series in a line chart. Is this also possible in the Xamarin Forms version?

On the Android calendar there's a line between the title and the day names. How do I remove this? I can't see a setting on CalendarDayCellStyle to do this.

Hi

1. I am using SplineAreaSeries to show a line with the area below fill in color.

When my Y values are negative the area filled above the line and not below (see attached image)

I'm aiming to get something which will look closer to this (desired.jpg).

2. Can i use a gradient color for the fill?

Thanks

Roei

I still new to Xamarin Form and currently making an update to our App. One of the features, is to click the events on the list after the date is selected and send the user to a event listing for the selected event. I just can't seem to figure out what method to use to add a click event to the bottom list view of events. I can't find any documentation to add this feature; can someone point me in the direction or show me how to approach this. All my code is almost the same from CalendarWithEvents example

Hi

I'm trying to use the annotations. my x axis is date time.

When i try to add CartesianGridLineAnnotation i get the following error:

: The value: '0' provided for the annotation is incompatible with the selected axis.

When I try to add CartesianPlotBandAnnotation my content page is not loaded

 

when i tried to add CartesianPlotBandAnnotation to axis y which is numeric it worked fine.

Any suggestions? the annotations feature is crucial for my chart implementation.

 

Thanks

Hi,

 

RadMaskedInput does not have any properties of TextAlignment or PlaceholderTextAlignment.

Will these features be supported?

 

Thanks.

Hi - I was hoping to control the font (size/color/etc) and the format (e.g. use numbers like 1,2,3, etc instead of decimals like 1.0, etc) in the callout labels that appear above a bar series item.  Is that possible to do now via the XAML or will it be included in a future release?  This would add some shine to the charts that I am creating.

 Thanks -

Erik

Hi,

my app crash right at start even before any RadCalendarView is displayed on screen. The first page shown to the user doesn't even contain a calendarView, so my guess is that the app crash during the initializing of the telerik librairy. Everything works fine in emulators, but once I run it on a real device it crash.

My device is a Pixel C with Marshmallow (6.0.1)

Any Idea how to solve this?

I have added the Telerik control for rad autocomplete to my project and given it a list of objects.

The trouble is, when I am debugging my project, I keep getting the output: "[0:] Could not load image named: {0}:"

I am not looking to add images to the list; the objects do not have images; and I am not adding images to the suggestion item template.

I even get this issue when I made a list of strings for the control to search for.

 

01.<telerikInput:RadAutoComplete x:Name="SearchControl" Watermark="Search..."
02.                  HorizontalOptions="FillAndExpand" Margin="10,0,0,0"
03.                  TextSearchPath="SearchByThis"
04.                  CompletionMode="Contains">
05.     <telerikInput:RadAutoComplete.SuggestionViewHeight>
06.        <OnPlatform x:TypeArguments="x:Double" Android="200" WinPhone="400" iOS="400" />
07.     </telerikInput:RadAutoComplete.SuggestionViewHeight>
08.     <telerikInput:RadAutoComplete.SuggestionItemTemplate>
09.        <DataTemplate>
10.            <telerikInput:RadAutoCompleteLabel FontSize="18" HighlightColor="Black"
11.                       TextColor="Silver" VerticalOptions="Center" />
12.        </DataTemplate>
13.     </telerikInput:RadAutoComplete.SuggestionItemTemplate>
14.</telerikInput:RadAutoComplete>
