Adding Report Viewer Web Part to Default page programmatically

Question

I am new to Sharepoint. I need to know the best way to add a ReportViewWebPart to a page through C# code behind.

I have tried accessing the web part from WebPartCatalog. It leads me to the NullReferenceException.

Then I tried by creating instance for ReportViewerWebPart and add the properties for ReportPath, Title, etc., it leads me to Object Reference Not Set to an Instance of an Object exception.

But I could add other web parts to a page as normal.

try this code:

SPLimitedWebPartManager webParts = SPContext.Current.Web.GetLimitedWebPartManager("pathToPage",System.Web.UI.WebControls.WebParts.PersonalizationScope.Shared);
ReportViewerWebPart reportWP = new ReportViewerWebPart();
reportWP.Title = "Title";
reportWP.ToolBarMode = ToolBarDisplayMode.Full;
reportWP.ToolBarItemsDisplayMode = ToolBarItem.Export | ToolBarItem.Print | ToolBarItem.Zoom;
reportWP.AutoGenerateTitle = false;
reportWP.AutoGenerateDetailLink = false;
reportWP.KeepSessionAlive = false;
reportWP.ScrollBars = ScrollBars.Vertical;
reportWP.ReportPath = "report.rdl";
webParts.AddWebPart(reportWP, "Body", 1);
