IFrame on Master Page is not functioning.
Iframe on a ASP.net Master page is giving me an error when I set to the Src property dynamically.
I have a website where the Master page has a Iframe defined. The idea is when ever the user choose a menu option, the asp.net page to be open is set to the SRC property in the back end of the Master page file.
In the code behind, i am setting the value as follows:
iMainFrame.Attributes.Add(
I am getting an error "Object reference not set to an instance of an object."
This issue happens only when I am using Master page and it works fine for a asp.net page with a Master file.
Any help is greatly appreciated.
Below is the master page definition.
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:Scrip
<div>
<asp:ContentPlaceHolder ID="MainContent" runat="server">
<iframe id="iMainFrame" src="SearchBuddy.aspx" style="border:none;width:1
</asp:ContentPlaceHolder>
</div>
</form>

Nope it is not working.
Alright. Please check the console (CTRL + SHIFT + I or F12) and tell me if you see any errors in there.

I found the issue.
When I moved the iframe definition outside the ContentPlaceHolder, it did work.
<iframe id="iMainFrame" src="SearchBuddy.aspx" style="border:none;width:1
<asp:ContentPlaceHolder ID="MainContent" runat="server"> </asp:ContentPlaceHolder>
</iframe>

When you use Master Pages, additional containers are added and by design ASP.Net will prefix your control name with those container names. To by pass this, you can force static(i.e. ASP.Net does not modify control's id that you have assigned) Ids.
