How to set the maximum level of row nesting

[Jorge Alberto]

Hello everybody

There is a standard way to set the maximum level of row nesting? For example two or three levels max.
I hope you can help me.

Best regards

Hello Jorge Alberto,

 You would  better set the maximum level of row nesting at data level.

For example if the GridView is bound to Items=ObservableCollection<Item>, then your code may look like:

public class Item

   {

       public string Name { get; set; }

       public int Level { get; set; }

 

       private ObservableCollection<Item> items;

       public ObservableCollection<Item> Items

       {

           get

           {

               if (items == null && this.Level < 2)

               {

                   items = new ObservableCollection<Item>(from c in Enumerable.Range(0, 10) select new Item(this.Level + 1));

               }

 

               return items;

           }

       }

 

       public Item(int level)

       {


           Name = "Name " + DateTime.Now.Ticks;

           Level = level;

       }

   }

<telerik:RadTreeListView ItemsSource="{Binding}" >
            <telerik:RadTreeListView.ChildTableDefinitions>
                <telerik:TreeListViewTableDefinition ItemsSource="{Binding Items}"></telerik:TreeListViewTableDefinition>
            </telerik:RadTreeListView.ChildTableDefinitions>
</telerik:RadTreeListView>

Let me know in case you have any further questions.
