This should be an easy answer, but i'm having problems finding the answer.
I have set a session variabel named Session["ynEdit"] that has the value of
True or False;
Session["ynEdit"] = true;
I'm using this value to determine whether or not textboxes should be
readOnly or not. The code i'm using for the textboxes is:
<asp:textbox id="id" runat="server"
ReadOnly='<%=Convert.ToBoolean(Session["ynEdit"])%>'>

I've also used

<asp:textbox id="id" runat="server" ReadOnly='<%Session["ynEdit"]%>'>

I keep getting the same result (see below) Thanks in advance.

Here's one way:

Thanks Ken.
I solved the problem taking a different approach

public void makeReadOnly()
{
foreach (System.Web.UI.Control c in this.Controls)
{
if (c.GetType().ToString().Equals("System.Web.UI.WebControls.TextBox"))
{
((TextBox)c).Attributes.Add("ReadOnly",Convert.ToString(true));
}
}

}

Thanks again,
Lyndon
