Close/Open Web Parts Programmatically

I didn't see a lot of post that shows you how to close and open web parts programmatically. I figured I'll writer one just in case I forget how to do it later.

You have to work with WebPartManager class for working with web parts. To get the web part manager, you can do the following:

SPFile page = site.GetFile("pageUrl")
SPLimitedWebPartManager webPartMngr = page.getLimitedWebPartManager(PersonalizationScope.Shared);

Once you have the WebPartManager, you can get the web part that you want to close by doing:

Foreach (WebPart webPart in webPartMngr.WebParts)
{
if (webPart.Title == "testWebPart")
{
webPartMngr.CloseWebPart(webPart);
webPartMngr.SaveChanges(webPart);
}
}

The SaveChanges() has to be done else it just won't work. After the web part is closed, you can still find it in webPartMngr.WebParts collection to re-open it. The code is basically the same as how you would close it. Just change the CloseWebPart() to OpenWebPart() instead.
