Inline asp.net code in server control tag?

[Darrel]

I need to take a querystring value of the page I'm on:

<%=Request.QueryString["itemid"].ToString()%>

and put it into a value within a server control tag:

<mytag:displayHTML id='myID' runat='server'
RequestURL='http://localhostexample.aspx?format=html&page=overview&id=<%=Request.QueryString["itemid"].ToString()%'
/>

Alas, that syntax doesn't work. Can it be done?

The problem is that code <%= ...%> is executed during rendering and
RequestURL="....." is needs to be done during parsing.

so you have 2 options.
1. Use data binding. <%# ...%>
RequestURL='<%#
"http://localhostexample.aspx?format=html&page=overview&id=" +
Request.QueryString["itemid"] %>'

2. Assign RequestURL in runtime
Page_OnLoad()
{
myID.RequetURL =
"http://localhostexample.aspx?format=html&page=overview&id=" +
Request.QueryString["itemid"];
}


PS: You do not need a ToString(). Request.QueryString["itemid"] already
returns a string.
