    copied!<p>I suppose this isn't a huge deal, since there are other way around this issue, but I'm really curious as to the answer, since I thought this was possible to do.</p> <p>I have a public property that returns a boolean in my code behind. I'd like to access this server variable in my javascript validation function, but so far, not quite getting it.</p> <pre><code>Public Property editMode() As Boolean Get If Cache("editMode") IsNot Nothing Then Return (DirectCast(Cache("editMode"), Boolean)) Else Return False End If End Get Set(ByVal value As Boolean) Cache("editMode") = value End Set End Property function validateEdit() { alert("editMode value is " + '&lt;%#editMode()%&gt;'); if ('&lt;%#editMode()%&gt;'.toString() == "True") { alert("You are currently in edit mode. Please save or cancel changes."); return false; } return true; } </code></pre> <p>I've tried a bunch of variations on this, but it's always False. In the current code the alert returns "editMode value is False"</p> <p>When I use:</p> <pre><code>if ('&lt;%#editMode()%&gt;') ... </code></pre> <p>Then it's still always False, but it goes into the if condition, so the behaviour is as if it were always true.</p> <p>One other thing to mention is that most javascript/server tag stuff I find says to use <strong>&lt;%=editMode %></strong>, but I can't do this because every time I use the = instead of the # I get an exception: </p> <blockquote> <p>"The Controls collection cannot be modified because the control contains code blocks (i.e. &lt;% ... %>)."</p> </blockquote> <p>So I solved this by using # and saying </p> <pre><code> Page.Header.DataBind() Page.Form.DataBind() </code></pre> <p>In the page load event handler.</p> <p>Any ideas? Thank you in advance. :)</p> <p>(Also, I usually use C#, so I might have unknowingly done something goofy in the VB part, so feel free to point that out too)</p>
