Add summary task to task list programatically

When we add summary task we need to ensure that we add it as a folder because summary task is not the alone list item type. it is actually a folder which contains another sub tasks.


Hence we can add summary task like this. I am taking an example of button click.



        protected void btnAddSummaryTask_Click(Object sender, EventArgs e)
        {
            SPList myList = SPContext.Current.Web.Lists["Tasks"];
            SPContentType type = myList.ContentTypes["Summary Task"];
            SPListItem newItem = myList.Items.Add("{site url}/Lists/Tasks", SPFileSystemObjectType.Folder, "Summary Task Title");
            newItem["ContentTypeId"] = type.Id;          
            newItem["Body"] = "This is a sample description"; 
            //Set another fields as needed.
            newItem.Update();
        }
