I am trying to access my hiddenfield values from code behind but I got empty values instead, what I am doing here is setting the 2 hiddenfield values from a Javascript function and after that do a postback via asp:button click. Not sure what am I doing wrong here, please kindly assist: Thanks.\[code\] <form id="Form1" class="form" runat="server"> <p class="SearchAddress"> <asp:TextBox ID="searchTextField" runat="server" /> <label for="searchTextField"> Location</label> </p> <p class="Date"> <asp:TextBox ID="txtDate" runat="server">18/10/2012</asp:TextBox> <label for="txtDate"> Date</label> </p> <p class="TimeFrom"> <asp:TextBox ID="TimeFrom" runat="server">18:00</asp:TextBox> <label for="txtTimeFrom"> Time From</label> </p> <p class="TimeTo"> <asp:TextBox ID="TimeTo" runat="server">19:00</asp:TextBox> <label for="txtTimeTo"> Time To</label> </p> <p class="submit"> <asp:Button ID="btnCalculateCoordinates" runat="server" Text="Post It!" onClientclick="calculateCoordinates();" onclick="btnCalculateCoordinates_Click" /> </p> <asp:ScriptManager ID="ScriptManager1" runat="server" /> <asp:UpdatePanel ID="uppnlLatLong" runat="server" UpdateMode="Conditional"> <ContentTemplate> <asp:HiddenField ID="txtLatitude" runat="server" /> <asp:HiddenField ID="txtLongitude" runat="server" /> </ContentTemplate> </asp:UpdatePanel> </form> function calculateCoordinates() { var txtAddress1 = document.getElementById('<%=searchTextField.ClientID%>'); var txtLat = document.getElementById('<%=txtLatitude.ClientID%>'); var txtLng = document.getElementById('<%=txtLongitude.ClientID%>'); var address = txtAddress1.value + ', '; var geocoder; geocoder = new google.maps.Geocoder(); geocoder.geocode({ address: address }, function (results, status) { if (status == google.maps.GeocoderStatus.OK) { var location = results[0].geometry.location; txtLat.value = http://stackoverflow.com/questions/12661873/location.lat(); //SETTING THE HIDDENFIELD VALUE txtLng.value = location.lng(); //SETTING THE HIDDENFIELD VALUE } else alert('Opps, sorry but we are unable to locate' + $(txtAddress1).val()); }); } </script>\[/code\]
