[Syncfusion Support]

Answer:

we can refresh the particular node using nodeClicked() event. Here is the code snippet for your reference,

<EjsTreeView TValue="TreeItem" @ref="tree" SortOrder="@Syncfusion.EJ2.Blazor.Navigations.SortOrder.Ascending"> 

        <TreeViewEvents TValue="TreeItem" NodeClicked="nodeclick">TreeViewEvents> 

EjsTreeView> 

public void nodeclick( Syncfusion.EJ2.Blazor.Navigations.NodeClickEventArgs args) 

    { 

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

        // you can modified the node based on your requirement and refresh the particular node 

        // Here we can change the particular node icon to pdf and refresh it. 

        TreeData.Add(new 

        { 

           Icon ="pdf" 

 

        }); 

        this.tree.RefreshNode(args.Node,TreeData); 

    }
