  Auto refresh page because of web custom control.

  Jan 03, 2008 08:39 AM|LINK

   It's really difficult for me to know why. Please help me.

  I have a custom web control. In it's CreateChildControls(), I create a Webcontrols.Image img1   and  a HtmlGenericControl("div") div1.

  Problem is that:

          if I add img1 into div1, when I run "start debugging"  the page will automatically refresh one more time.

  But If I add another div or span into div1, it won't automatically refresh one more time.
   

  Here is code:

   public class CustomeUI : WebControl,INamingContainer, ICallbackEventHandler
   {

          protected override void CreateChildControls()
          {

            System.Web.UI.WebControls.Image img1 = new System.Web.UI.WebControls.Image();

            div1 = new HtmlGenericControl("div");

            div1.Controls.Add(img1);  // This is the problem. It will automatically refresh one more time when start debuging.
  

            this.Controls.Add(div1);

          }

  }
   

   Thanks in advance.

   Solved.

  I found it. Just assign ImageUrl properties to something.
