                CheckedChanged="CheckedChanged">
        <DataMappings>
            <DxTreeViewDataMapping Text="Name"
                                   Key="Id"
                                   ParentKey="CategoryId" />
        </DataMappings>
    </DxTreeView>
    
    @code {
        string? LastChecked = "none";
        void CheckedChanged(TreeViewCheckedChangedEventArgs e) {
            var lastCheckedNode = e.LastCheckedItems.LastOrDefault();
            LastChecked = lastCheckedNode != null ? lastCheckedNode.Text : "none";
        }
    }
