Content Template

Good Day

i am able to show images , video and normal text formatted based on my content templates. but it works well when loading the data in the chat control. When a User type a simple "hi" there is already a content template for outgoing messages which format this correctly when its load. my problem is that when they user type it does not use any of my content template

Author senderitem = new Author();

senderitem.Avatar = model.AUTHOR_PROFILE_PIC;

senderitem.Name = model.AUTHOR;

TextMessage textMessage = new TextMessage();

textMessage.Data = model.CHAT_MESSAGE;

textMessage.Author = senderitem;

textMessage.Text = model.CHAT_MESSAGE;

Device.BeginInvokeOnMainThread(() =>

{

chat.Items.Add(textMessage);

chat.Message = string.Empty;

});

Transition effect

Hi, it is possible to remove the transition effect on the RadTreeView? It's really annoying cause I have 500 items and it adds that bad delay.
Thank you Admins :D

TreeView Getting Started

Hi everybody. Im following the getting started guide here (https://docs.telerik.com/devtools/xamarin/controls/treeview/treeview-getting-started). I have a few question: First of all I need to create the class Item and ViewModel in the general folder of the project?

Then when I arrived at this step:

<telerikDataControls:RadTreeView x:Name="treeView" ItemsSource="{Binding Source}"><telerikDataControls:TreeViewDescriptor DisplayMemberPath="Name"ItemsSourcePath="Children"TargetType="{x:Type local:Item}" /></telerikDataControls:RadTreeView>

If I copy this inside my project and then compile I get this error: "Type Item not found in xmlns" at row 13 that is this line here TargetType="{x:Type local:Item}
What am I doing wrong?

I just want to put a treeview in the app but Im not able. I tried to create the classes under UWP files, I moved all down there, delete from the main Shared part of the project but nothing.
Images attached :D
Thank you
