  Here is an example that will add a WebpartZone into a TD and also add a GenericWebPart into the WebPartZone. The Zone's can't be added after the Page_Init event:

  <script runat="server">
  
  
      public void Page_Init()
      {
          Button button = new Button();
          button.ID = "testButton";
  
  
          WebPart myWebPart = WebPartManager1.CreateWebPart(button);
          WebPartZone zone1 = new WebPartZone();
          zone1.ID = "zone1";
  
  
          MyZone.Controls.Add(zone1);
  
  
          WebPartManager1.AddWebPart(myWebPart, zone1, 0);
      }
      
  
  </script>
  
  
  
  
      
  
  
      <form id="form1" runat="server">
      <div>
          
          
          
  
  
              
                  
              
          
      </div>
      </form>

  The WebPart should be kept on the page. The following code works just fine, when I change the mode to design mode, the WebPart is left on the page:

  <script runat="server">
  
  
      public void Page_Init()
      {
          Button button = new Button();
          button.ID = "testButton";
  
  
          WebPart myWebPart = WebPartManager1.CreateWebPart(button);
          WebPartZone zone1 = new WebPartZone();
          zone1.ID = "zone1";
  
  
          MyZone.Controls.Add(zone1);
  
  
          WebPartManager1.AddWebPart(myWebPart, zone1, 0);
      }
      
  
  </script>
  
  
  
  
      
  
  
      <form id="form1" runat="server">
      <div>
          
          
          
  
  
              
                  
              
          
      </div>
          
          
      </form>

  NOTE: Before you add a WebPart, make sure it not already added to the Zone. When a WebPart is added, the personalization feature of the WebPart feature will remember the added WebPart and the next time you visit the page, and when that happens, the code above will always add a new WebPart, so the next time there will be two WebParts on the page.

  usmanishaque: WebPartZons can't be added after the Page_Init event. SO if you add a button and try to add a WebPartZone from the button click event, an exception will be thrown.

  Sir I added WebPartZone on button click as I wrote code in Page init event code is void Page_Init(object sender, EventArgs e) { if (Request["var"]=="true") { WebPartZone zone1 = new WebPartZone(); zone1.ID = "osman"; zone1.Width = 100; zone1.Height = 100; zone1.EmptyZoneText = "Empty"; MyZone.Controls.Add(zone1); Response.Write("dfa"); var="false"; } } On click event i send var=true; Now I want to add WebPartZone in DB I think that can be done by adding WebPartZone to WebPartZoneCollection. Can I do by WebPartZoneCollection? Thanks Osman

  The WebPartZone will not be saved into a data source (Only the WebParts will be saved by the personalization feature of the WebPart framework), you have to handle that by your own.

  usmanishaque : If you don't add the WebPartZone in the Page_Init event or don't specify them on the page, they are basically removed because they don't exist. So to remove a WebPartZone, you simply do not add it to the page. > and change their positions like Webparts? If you are talking about the way you can drag & drop WebParts, the answer is no. You can probably write your own functionality that can do that, but by default, you can't move around WebPartZones like you can move around WebParts. WebPartZones are fixed zones on the page that is a container for WebParts, nothing more.
