How to: Work with Web Parts on a Page

SharePoint 2010

In this article
Updating the title of a Web Part
Adding a Web Part to a page
Deleting a Web Part from a page

Available in SharePoint Online

Use classes in the Microsoft.SharePoint.Client.WebParts namespace to work with Web Parts through the client object model. The LimitedWebPartManager class allows you to access the collection of Web Parts on a SharePoint page within a shared or personal scope through the WebParts property

The following example changes the title of the second Web Part in the collection of Web Parts on the Default.aspx page of the specified Web site. The example uses a LINQ query expression to return only the title of each Web Part, and calls the SaveWebPartChanges() method to save changes. The ExecuteQuery() or ExecuteQueryAsync(ClientRequestSucceededEventHandler, ClientRequestFailedEventHandler) method is called twice, first to return the collection of Web Parts so that the code can verify that Web Parts exist on the page, and second to effect changes in the database.

{
    class UpdateWebPartTitle

            File oFile = oClientContext.Web.GetFileByServerRelativeUrl("Default.aspx");
            LimitedWebPartManager limitedWebPartManager = oFile.GetLimitedWebPartManager(PersonalizationScope.Shared);

            oClientContext.Load(limitedWebPartManager.WebParts,
                wps => wps.Include(
                wp => wp.WebPart.Title));

            oClientContext.ExecuteQuery();

            if (limitedWebPartManager.WebParts.Count == 0)
            {
                throw new Exception("No Web Parts on this page.");
            }

            oWebPart.Title = "My New Web Part Title";

            oWebPartDefinition.SaveWebPartChanges();

            oClientContext.ExecuteQuery();

The following example adds a custom content editor Web Part as the second Web Part, in order, within the left zone of the Default.aspx page for a specified Web site. The example defines the XML for the Web Part, passes this string to the ImportWebPart(String) method, and then calls the AddWebPart(WebPart, String, Int32) method to add the Web Part to the page.

    class DeleteWebPart
