postback issue when using dynamically created datetimepicker using javascript

Dhyanga

Hi, I am using dynamic datetimepicker that the user can add to any number. But I am having postback problem. Once I submit it, the return page should have all the submitted values including those added dynamic datetimepicker. Right now when i submit and when the page returns, all other static controls with data are there but no dynamically added datetimepicker controls. Below is the code I used to add datatimepicker dynamically using javascript:

<html>

     var counter = 1;
      jQuery("#<%= btnD1Add.ClientID %>").click(function (event) {
        event.preventDefault(); //this code is added to prevent the default submit functionality of the button

        jQuery("*   ").appendTo(".Date1More");
            jQuery("<label id='lblD1StartTime" + counter + "'>StartTime:</label><input type='text' id='txtD1StartTime"  +counter + "' name='txtStartTime1'/>").timepicker({
                hourGrid: 10,
                minuteGrid: 10,
                timeFormat: 'hh:mm tt'
            }).appendTo(".Date1More");
            
            counter++;
        });
    });
</script>

</html>

Now how to use postback for these controls? I had tried to use following code in code but didn't work. I even tried it using !Ispostback() function under pageLoad but no effect.

protected string[] txtStartTime1;
protected void Page_Load(object sender, EventArgs e)
{

        txtStartTime1 = Request.Form.GetValues("txtStartTime1");
    }

protected void Page_Init(object sender, EventArgs e)
{

To understand this behaviour you need to understand page life-cycle properly. I can't explain the whole stuffs here but would recommend you to read it.

Yes, you can very well avoid postback by using ajax or PageMethods. Just see which is best suited in your scenario.

Thank you very much Anurag. I don't know why I didn't think of using Ajax before I spent lots of time thinking on this. :)
