Hi Jacky, Greetings from Syncfusion support. We have checked your reported query with TreeView component. In TreeView, we have provided a two way binding support for selectedNodes property in the release version (18.3.41) Please, refer the below release notes. https://blazor.syncfusion.com/documentation/release-notes/18.3.41/?type=all#treeview To resolve your issue, you need bind the selectedNodes property as per the below code snippet in your application. public string[] selectedNodes { get; set; } // Triggers when TreeView node is clicked public void nodeClicked(NodeClickEventArgs args) { selectedId = args.NodeData.Id; selectedNodes = new string[] { selectedId }; } For your reference, we have prepared a sample for TreeView with context menu. Please, refer the sample link below. https://www.syncfusion.com/downloads/support/forum/160172/ze/TreeView-1855732381.zip If the issue still persist, please replicate the issue in attached sample. It would help us to provide you prompt solution. Please let us know, if you need any further assistance. Regards, Sowmiya.P
