SlideView

Button clicked event  property doesn't work inside Slideview.

Hello Nethra,

This is expected because ContentViews are not in the same scope as that page's code behind.  So that you can understand the infrastructure of the RadSlideView and not get stuck with the issue in the future, Let me explain further.


All the ContentViews in a SlideView.ItemsSource do not share any BindingContext or scope with that page it is defined on. If you need event handler, then you'll want to redefine the ContentView in a separate file and use the event handler in the ContentView's code-behind.

For example

<ContentView x:Class="myApp.Views.MyContentView" .... >
    <Grid>
        <Button Cliecked="OnClicked" />
    </Grid>
<ContentView>

using Xamarin.Forms;

namespace MyApp.Views
{
    public partial class MyContentView : ContentView
    {
        public MyContentView()
        {
        }

        public void Onclicked(object sender, EventArgs e)
        {

        }
    }
}

Then you can use an instance of that ContentView in the SlideView

<telerikPrimitives:RadSlideView x:Name="slideView">
    <telerikPrimitives:RadSlideView.ItemsSource>
        <x:Array Type="{x:Type ContentView}">
            <myViews:MyContentView />
        </x:Array>
    </telerikPrimitives:RadSlideView.ItemsSource>
</telerikPrimitives:RadSlideView>

If you need interaction between the SlideView and the page's binding context, you could create a global static helper class that both the ContentView and the Page have access to.
