Add runat="server" attrubute to your iframe and access it on code behind like this :

iframe.src="testpage.aspx"

Page Redirect to the URL , rather than it loads the iframe in the same page itself

i am reading pdf files saved on MSSQL server in form of byte array and trying to display in iframe. I am facing the problem. the first file I had opened is opening again and again even deleting cookies and clear up the temp folder. the code I am using is as below:

Dim RID As String
RID = Request.QueryString("RPTID")
Dim rptProp() As String = RPT.getReport(CInt(RID))
'Me.docContent.Attributes.Item("src") = ""
If rptProp(6) <> "" Then
Filename = rptProp(7)
Me.Filename = Filename
Me.Extension = Mid(rptProp(7), rptProp(7).IndexOf("."c) + 2, rptProp(7).Length)
Dim doc() As Byte = Nothing
doc = RPT.getRepDoc(CInt(RID))
If doc IsNot Nothing Then
If Extension = "pdf" Then
Dim base64String As String = Convert.ToBase64String(doc, 0, doc.Length)
Dim pdfIFrameSrc = "data:Application/pdf;base64,{0}" + base64String

' set the src attribute
Me.docContent.ResolveUrl(pdfIFrameSrc)
End If
End If

Solution 3

also try this code

HtmlControl MyFrame = (HtmlControl)this.FindControl("urIFrameName");
     MyFrame.Attributes["src"] = "yourPageName.aspx";

If we code like this , it shows an error Object reference ha not been set

Solution 2

try this:
Add runat="server" attribute to your iframe.

ASP.NET

<iframe id="urIframe" runat="server"></iframe>

Once you add runat="server" attrubute to your iframe you can access your iframe from codebehind.

Now add src attribute from codebehind:

C#

urIframe.Attributes.Add("src","http://www.facebook.com");

Good luck.

Pavan Kumar, this works well locally, but on server I got an exception.
A possible dangerous Request.Path value was detected on the client (:).
Do you have any idea?

Why are you using colon(:) character in your path? : is not allowed in the path of the url.

Solution 1

XML

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";
    }

OR

HTML :

<iframe id="gameframe" runat="server" width="1000" height="500" align="middle" src=""></iframe>

This.gameframe.Attributes("src") = "game url";
