I am just trying to display a "Loading" progress bar on every postback.

These are the things i have tried so far.
1. Using Update panel to display the progress bar.(This works only with update panel).
2. Displaying a Fake jquery progress bar(This is not specific with the time being consumed with the actual postback caused by any control in my webpage.)

But the below is what i am trying to implement.

protected void Button1_Click(object sender, EventArgs e)
 {
    startProgressBarOnBeginRequest(this.Page,sender)
    //button1_click code execution..
    endProgressBarOnEndRequest(this.Page,sender)
 }

public void startProgressBarOnBeginRequest(Page page,object sender)
 {
    //show loading image here{Image1.Visible=true}=>this wont work
    //??? how
 }
 public void endProgressBarOnEndRequest(Page page, object sender)
 {
    //hide loading image here{Image1.Visible=false}=>this wont work
    //??? how
 }

I want startProgressBarOnBeginRequest() and endProgressBarOnEndRequest() these 2 methods to execute whenever a postback event happens by any control..

is there anything that i need to do in global.asax? {Application_Start and Application_End events}

Thanks in advance.
