In this blog, we will see the piece of the code to export the web part in a web part page. A SharePoint Web part is a piece of server code which does the certain functionality like listing your site assets. A SharePoint web part can be dragged and dropped into any Web Part Zone. Here is the piece of code to achieve the functionality of exporting it.

SPSecurity.RunWithElevatedPrivileges(delegate()
{
foreach (string Title in webPartTitles)
   {
     foreach (System.Web.UI.WebControls.WebParts.WebPart webPart in wpManager.WebParts)
        {
                // Find the matched closed web part in WebParts collection

               if (webPart.Title == Title && webPart.IsClosed == true)
               {
            
            MemoryStream stream = new MemoryStream();
             XmlTextWriter writer = new XmlTextWriter(stream, System.Text.Encoding.UTF8);
              webPart.ExportMode = WebPartExportMode.All;

    // Export the closed webpart to a memory stream.
       wpManager.ExportWebPart(webPart, writer);

                   writer.Flush();
                  stream.Position = 0;

              XmlTextReader reader = new XmlTextReader(stream);

          // Import the exported webpart.
              System.Web.UI.WebControls.WebParts.WebPart newWebPart = wpManager.ImportWebPart(reader, out errorMessage);

               reader.Close();
               writer.Close();

       // Show the imported webpart.
          panel.Controls.Add(newWebPart);
          break;
           }
    }
}

In this code, make sure that your Webpart export mode is set to all. By Default it is set to None. Happy SharePointing Folks 🙂
