asp.net cs variable in aspx page

Need some help please. I've got an aspx page with an iframe and I'm trying to pass a variable called 'pageId' from my code behind to it. I've looked at various examples on SO and other sites and most suggest to others its a databinding issue and I've followed through some of the examples. Perhaps I can't use a variable like the way Im trying to do in an iframe?

I've introduced the get/set and public properties, but just a little lost. Anyone help point me in the right diection please?

aspx page

<iframe width="690" height="600" src="https://myserver.com/Index.php?pageId=<%=pageId%>" frameborder="0" scrolling="yes" style="border-width: 0px;"></iframe>

aspx.cs page

protected String pageId { get; set; }

//private string pageId;
//public String pageId { get {return pageId; } }

protected void Page_Load(object sender, EventArgs e)
{
    string pageId = 'Y2840'; //this is generated from my db and I know the data is being stored in here as I have Response.Write(pageId)   
}

Your private variable and public property have the same name. Try using a capital P in your property name. Also don't declare a new variable pageId in Page_Load. PageId is blank because you are setting the local Page_Load method variable, and not the class level variable.

private string pageId;
public string PageId { get {return pageId; } }

protected void Page_Load(object sender, EventArgs e)
{
    pageId = 'Y2840';  
}

In your aspx page:

<%=PageId%>

method 1.

<iframe runat="server" id="myiframe" width="690" height="600"      
frameborder="0" scrolling="yes"     style="border-width: 0px;"></iframe>

code-behind:

myiframe.src="https://myserver.com/Index.php?pageId=" + pageId;

method 2.

put iframe in formview and give it a datasource. Then use your existing code.
