How to close the opened project items when we create the project from VSIX

Hi,

When I create the project via my own project templates the project items are opened  automatically. I have added my project items dynamically using the below function 

 wizardproject.ProjectItems.AddFromFile(filePath+fileName);

It will be added correctly but the projects items tree expanded automatically. I have attache the screen shot. How can I avoid this? 

Thanks,
