copied!<p>OK so the basic problem here is that if you use an inline expression you can NOT use it to set a property of a server-side control outside of a binding context (using a binding expression). I have inferred that this is probably because of the timing of the evaluation of these inline expressions. You can, however, render client-side markup in this way. If you want to keep the functionality purely in your aspx file, this is the way to do it.</p> <p>Edit: Based on input from Justin Keyes, it appears it IS possible to use a binding expression to set the property. You need to manually invoke <code>Page.DataBind()</code> to trigger the textbox to evaluate the expression (see answer below).</p> <p>For instance this:</p> <pre><code><asp:Label ID="lbl" runat="server" Text="<%= Now.ToShortDateString() %>" /> </code></pre> <p>Will produce this output:</p> <blockquote> <p><%= Now.ToShortDateString() %></p> </blockquote> <p>On the other hand this:</p> <p><code><%= "<span>" & Now.ToShortDateString() & "</span>"%></code></p> <p>Will produce this output:</p> <blockquote> <p>7/27/2011</p> </blockquote> <p>The "normal" way to solve this problem is just to set the <code>Label.Text</code> properties in a <code>Page.Load</code> event handler or another appropriate event handler depending on your needs, as below. This is the way I believe most people would prefer to do it, and is most easily understandable in my opinion.</p> <p>Markup:</p> <pre><code><asp:Label ID="lbl" runat="server" /> </code></pre> <p>Code:</p> <pre><code>Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load lbl.Text = Now.ToShortDateString() End Sub </code></pre>
