Thanks a lot in advance

I suggest that you use web user controls with .ascx extension instead of iframes. I can tell you how to do what you want with iframes too but it there will be unnecessary details. You can dynamically load the web user controls to different sections of web forms easily.

Please try this code :

IFrame.Attributes("src") = "Folder\details.aspx"

Thanks.

Right click to your project choose add new item, select web user control, put what you put in your iframes. then drag and drop the web user control on to your web page(where you would put your iframe). if you want to add the web user control dynamically, add an asp panel control to your page then onload event of your panel control type this : myPanel.Controls.Add(LoadControl("WebUserControl.ascx")); .

Page:

<form id="Form1" method="post" runat="server">
<iframe id="ifrm" runat="server"></iframe>
</form>

Codebehind:

using System.Web.UI.HtmlControls;

public partial class test : System.Web.UI.Page
{
  
    protected void Page_Load(object sender, EventArgs e)
    {
       
       ((HtmlControl)(form1.FindControl("ifrm"))).Attributes["src"] = "http://www.yahoo.com";
    }

iframe.Attributes("src") = "Adminpanel.aspx";
how to declare iframe in aspx page it gives does not exist in the current page
