Adding a webpart
Today I tried to add a web part to a page using the following code:
ListViewWebPart webpart = new ListViewWebPart();
webpart.Title = "Matter Emails";
webpart.ListName = item.ListItems.List.ID.ToString("B").ToUpper();
webpart.ViewGuid = item.ListItems.List.Views["All Emails"].ID.ToString();
webpart.Visible = true;
WebPartManager.AddWebPart(webpart, "TopLeftRow", 1);
WebPartManager.SaveChanges(webpart);
This gave me a “The specified view is invalid” Exception on the AddWebPart call.
The specified view is invalid in call to LimitedWebPartManager.AddWebPart
Your Solution
Then I moved the following line:
webpart.ViewGuid = item.ListItems.List.Views["All Emails"].ID.ToString();
resulting in
ListViewWebPart webpart = new ListViewWebPart();
webpart.Title = "Matter Emails";
webpart.ListName = item.ListItems.List.ID.ToString("B").ToUpper();
webpart.Visible = true;
WebPartManager.AddWebPart(webpart, "TopLeftRow", 1);
webpart.ViewGuid = item.ListItems.List.Views["All Emails"].ID.ToString();
WebPartManager.SaveChanges(webpart);
and the web part was added to the page with the correct view.

Thanks, this was super helpful. SP makes me nervous sometimes… the same code that was working in MOSS2007 does not working in SP2016, because of the ordering within the code!
