google map api v2
<p>I've problem calling gdrirection.load(),if I specified the values it'll work ,but if I pass them through text boxes it doesn't work.
here's my code </p>

<pre><code>var map;
    var directionsPanel;
    var directions;
function initialize() {

        if (GBrowserIsCompatible()) {
            map = new GMap2(document.getElementById("map"));
            map.setCenter(new GLatLng(24.7116667, 46.7241667), 12);
            map.setUIToDefault();
            var txtAddress = document.getElementById('txtAddress').value;
            var TextBox1 = document.getElementById('TextBox1').value;
            directions = new GDirections(map, directionsPanel);
            directions.load("from: 'TextBox1' to: 'txtAddress'");        
        } 
    }
&lt;body onload=initialize()&gt;

            &lt;asp:TextBox ID="txtAddress" runat="server" Visible="true" /&gt;
            &lt;input type="button" value="direction" onclick="initialize();" title="direction"  /&gt;
            &lt;asp:TextBox ID="TextBox1" runat="server" Visible="true"&gt;&lt;/asp:TextBox&gt;`
</code></pre>

<p>Thanks</p>
