Hi

I've created a Bubble chart using Google Chart. When user clicks on a bubble I call __doPostBack() function using javaScript to post-back the selected value to the server. Here is an excerpt from  my code:

// Instantiate the visualization (BubbleChart) in a div element
            chart = new google.visualization.BubbleChart(document.getElementById('chart_div'));

            // The event handler, selectHandler(), calls the chart's getSelection() method
            function selectHandler()
            {
                var selectedItem = chart.getSelection()[0];
                if (selectedItem)
                {
                    var value = selectedItem.row; //, selectedItem.column);
                    document.getElementById('txtDistance').value = 'You have selected ' + data.D[value].c[0].v;
                    __doPostBack('txtDistance','');
                 }
                var selection = chart.getSelection();
            }

            // Listen for the 'select' event, and call my function selectHandler() when
            // the user selects something on the chart.
            google.visualization.events.addListener(chart, 'select', selectHandler);

As you can see that the javascript is assigning a value to the the TextBox 'txtDistance' (the TextBox 'txtDistance' has an  associated TextChanged event) and calling the __doPostBack function to trigger the event procedure 'txtDistance_TextChanged()'

Everything works fine until I add an AJAX ScriptManager ( <asp:ScriptManager ID="ScriptManager1" runat="server" />) in the form.

Can anyone explain why is this happening please?
