Access to tree in razorpage code when using UrlAdaptor to get remote data?

[MikeR]

When I try treeView.AddNodes,in the razor code, after fetching data successfully using the UrlAdaptor, I can't get the UI to update with new node. The code below just gets the root node independent of what the tree looks like:

List<object> treeData = await treeView.GetTreeData();

Hi Mike, 

Greetings from Syncfusion. 

You can dynamically add the tree nodes via AddNodes method using the following code snippet. 

public void addNodes() 

{ 

     List<object> listdata = new List<object>(); 

     listdata.Add(new 

        { 

            employeeID = this.index, 

            firstName = "NewItem", 

        }); 

         this.tree.AddNodes(listdata); 

         this.index = this.index + 1; 

} 

 

Kindly ensure once whether you provided the same id and text field as same as the initial mapping.
