Hi everyone,
I can export the whole map image file now using the code below.
using (Stream stream = dialog.OpenFile())
{
    FrameworkElement element = this.m_Radmap.FindChildByType<ItemsPresenter>();
    Telerik.Windows.Media.Imaging.ExportExtensions.ExportToImage(
        element, stream, new PngBitmapEncoder());
}

But the problem is that I have added a few marks on radmap information layer.
How to export these marks together with the map image?

Hello Hongyi,

We noticed that you're exporting the ItemsPresentr within the RadMap and if you'd rather export only the Map content and its InformationLayer, then I'd suggest hiding elements like map navigation, map scale etc.

You can hide them before export using the following code:

this.m_Radmap.NavigationVisibility = System.Windows.Visibility.Collapsed;
this.m_Radmap.CommandBarVisibility = System.Windows.Visibility.Collapsed;
this.m_Radmap.ZoomBarVisibility = System.Windows.Visibility.Collapsed;
this.m_Radmap.ScaleVisibility = System.Windows.Visibility.Collapsed;
this.m_Radmap.MouseLocationIndicatorVisibility = System.Windows.Visibility.Collapsed;
this.m_Radmap.MiniMapExpanderVisibility = System.Windows.Visibility.Collapsed;
using (Stream stream = dialog.OpenFile())
{
    ExportExtensions.ExportToImage(
        this.m_Radmap, stream, new PngBitmapEncoder());
}
 
this.m_Radmap.NavigationVisibility = System.Windows.Visibility.Visible;
this.m_Radmap.CommandBarVisibility = System.Windows.Visibility.Visible;
this.m_Radmap.ZoomBarVisibility = System.Windows.Visibility.Visible;
this.m_Radmap.ScaleVisibility = System.Windows.Visibility.Visible;
this.m_Radmap.MouseLocationIndicatorVisibility = System.Windows.Visibility.Visible;
this.m_Radmap.MiniMapExpanderVisibility = System.Windows.Visibility.Visible;

Please let me know if that helps or if we can further assist you.
