Hi Diogenis, 
 
Thank you for using Syncfusion products. 
 
We have checked the reported query “Is it possible to sum all rows height?” from our side. We would like to inform you that you can get the total height of the SfListView from the TotalExtent value.  
 
Please refer to the following code snippets for more reference, 




public class ExtendedListView : SfListView 
{ 
    VisualContainer container; 
    public ExtendedListView() 
    { 
        container = this.GetVisualContainer(); 
        container.PropertyChanged += Container_PropertyChanged; 
    } 
 
    private void Container_PropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e) 
    { 
        double totalHeight = 0; 
        Device.BeginInvokeOnMainThread(async () => 
        { 
            var extent = (double)container.GetType().GetRuntimeProperties().FirstOrDefault(container => container.Name == "TotalExtent").GetValue(container); 
            if (e.PropertyName == "Height") 
                totalHeight = extent; 
        }); 
    } 
} 
 
Please refer to online documentation to load the ListView with full height,
