Adding a tree node

Hello, I'm new to matlab. I need a help on how to add a tree node in the panel. My issue is I get the list of data from the server, I need to represent the list in treenode format in the UI. My code for Preview tree is

        Root=uitreenode('v0','Database Preview','Database Preview',[],false);
        [dbPreviewTree,dbPreviewContainer] = uitree('v0', 'Root',Root, 'Parent',SDBPanel);       
        dbPreviewTree.setMultipleSelectionEnabled(true);
        dbPreviewTree.expand(Root);
        jdbcPropsTablePos=get(jdbcPropsTable,'Position');
         set(dbPreviewTree,'Units','normalized',  'Position',[jdbcPropsTablePos(1) jdbcPropsTablePos(2)-30 jdbcPropsTablePos(3) 30])
        set(dbPreviewContainer,'Parent',SDBPanel,'Units','characters',...
            'Position',[jdbcPropsTablePos(1) jdbcPropsTablePos(2)-30 jdbcPropsTablePos(3) 30])        
        handles=getWVHandles;
        handles.dbTree=dbPreviewTree;
        guidata(findobj('Tag','MainFigure'),handles);
To create a Node my code is:
%%Create database nodes
        databaseNodes=cell(size(databaseList,1),1);
        for dbL=1:size(databaseList,1)
            databaseNodes{dbL}=uitreenode('v0',databaseList{dbL},databaseList{dbL},[],false);
            if isempty(schemaStruct{dbL})==0
                schemaNodes=cell(length(schemaStruct{dbL}.schemas),1);
                for scL=1:length(schemaStruct{dbL}.schemas)
                    schemaNodes{scL}=uitreenode('v0',schemaStruct{dbL}.schemas{scL},...
                        schemaStruct{dbL}.schemas{scL},[],false);
                    databaseNodes{dbL}.add(schemaNodes{scL});
                    tableNodes=cell(length(tableStruct{dbL}{scL}),1);                    
                    if isempty(tableStruct{dbL}{scL})==0
                     for taL=1:length(tableStruct{dbL}{scL}.tables)
                     tableNodes{taL}=uitreenode('v0',tableStruct{dbL}{scL}.tables{taL},...
                                tableStruct{dbL}{scL}.tables{taL},[],true);
                            schemaNodes{scL}.add(tableNodes{taL});
                        end
                    end
                end
            end
            Root.add(databaseNodes{dbL})
        end
        dbPreviewTree.reloadNode(Root);

Please help!
