Hi,


I have created an expander view in my app.I have around 5k subitems for a header.The app gets crashed when the header is expanded.To just verify this, I have tried to display 500 subitems,it worked but took time to get expanded.Kindly help me if I can display 5K records with the help of expander view without taking time.My code is:


               
                   
                       
                   
                   
                       
                           
                       
                   
                   
                       
                           
               
                IsNonExpandable="{Binding HasNoOptions}" IsExpanded="{Binding IsExpanded, Mode=TwoWay}" HeaderTemplate="{StaticResource CustomHeaderTemplate}" ExpanderTemplate="{StaticResource CustomExpanderTemplate}" 
                ItemTemplate="{StaticResource CustomItemTemplate}" NonExpandableHeaderTemplate="{StaticResource CustomNonExpandableHeaderTemplate}" Style="{StaticResource ExpanderViewStyle1}" />
                         
                       
                   
               
           


 this.orderList.ItemsSource = myList;
