Adding Webpart to the Page Programatically in SharePoint

Hi All,

Here I am explaining you how to add a web part to the page programatically.  For this demo I have created a web part page called Demo.aspx  and I am adding a content editor web part to this page through programatically. 

For this first we need to get the reference of the SPLimitedWebPartManager  of the page where we are going to add the webpart.

Here is the code

protected void Addwebpart_Click(object sender, EventArgs e)

        {           

            using (SPSite site = new SPSite(SPContext.Current.Site.ID))

            {

                using (SPWeb web = site.OpenWeb())

                {

                    web.AllowUnsafeUpdates = true;

                    //getting reference of SPLimitedWebpartManager of the page

                    SPLimitedWebPartManager wpManager = web.GetLimitedWebPartManager("http://sp2010:9999/SitePages/Demo.aspx", System.Web.UI.WebControls.WebParts.PersonalizationScope.Shared);                   

                    //Creation of ContentEdiotr Webpart

                    ContentEditorWebPart myCEWP = new ContentEditorWebPart();

                    myCEWP.ID = "myCEWP";

                    myCEWP.Title = "Demo Content Editor";

                    //Adding Webpart to the page

                    wpManager.AddWebPart(myCEWP, "Main", 1);

                    wpManager.SaveChanges(myCEWP);

                }

            }

        }

If you want to add the Shared Documents (ListView webpart) to the page,  Here is the way..

                    web.AllowUnsafeUpdates = true;

                    SPList lstCDD = web.Lists.TryGetList("Shared Documents");

                    if (lstCDD != null)

                    {

                        SPLimitedWebPartManager wpManager = web.GetLimitedWebPartManager("http://sp2010:9999/SitePages/Demo.aspx", System.Web.UI.WebControls.WebParts.PersonalizationScope.Shared);

                        XsltListViewWebPart webpartCDD = new XsltListViewWebPart();

                        webpartCDD.ListName = lstCDD.ID.ToString("B").ToUpper();

                        webpartCDD.ViewGuid = lstCDD.DefaultView.ID.ToString("B").ToUpper();

                        wpManager.AddWebPart(webpartCDD, "Main", 2);

                        wpManager.SaveChanges(webpartCDD);

                    }

Here the AddWebpart method expects three parameters, webpart, zoneid(string-Id of the webpartzone where the webpart is being added to like Main, Left etc), zone index(Int-Index of the zone like 1,2,3..)

Cheers,
