    I was going to use the SlideView to show images.  What is the best image size to use?

    Hi David,

    This is entirely up to the target platform and even which device on that platform. Every device has a different pixel density and resolution.

    If you're looking for what the dimensions might be in the area, you could do a test like this and see the values for each platform:

    <telerikPrimitives:RadSlideView x:Name="SlideView" HorizontalContentOptions="Fill" VerticalContentOptions="Fill">
                <Grid x:Name="TemplateRoot">
                    <StackLayout HorizontalOptions="Center" VerticalOptions="Center">
                        <Label Text="{Binding Width, StringFormat='Width: {0:N2}', Source={x:Reference TemplateRoot}}" />
                        <Label Text="{Binding Height, StringFormat='Height: {0:N2}', Source={x:Reference TemplateRoot}}" />


    If you want more control over the image's rendering, you could use a 3rd party image control to restrict the resolution of the image. A popular option is FFImageLoading, scroll down and read the Downsample properties in this documentation.

    If you have any trouble using images in the ItemTemplate, please open a support ticket here and attach your code so we can investigate directly.
