How to attach Timer to a button using C#

I'm having a timer(with label) and a button on one of my pages. The timer is using a simple onTickEvent.

  protected void Timer1_Tick(object sender, EventArgs e)
    {
        int seconds = int.Parse(Label1.Text);

        if (seconds > 0)

            Label1.Text = (seconds - 1).ToString();
        else
            Timer1.Enabled = false;
    }

all the extensions are grouped together in an UpdatePanel

 <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
                <asp:UpdatePanel ID="UpdatePanel1" runat="server">
                    <ContentTemplate>
                        <asp:Button ID="schlbtn1" runat="server" Text="Go To Lectures" CssClass="btn btn-lg btn-success btn-block" OnClick="schlbtn1_Click" Visible="true" ForeColor="Black" ViewStateMode="Enabled" ClientIDMode="Static" />
                        <asp:Label ID="Label1" runat="server">60</asp:Label>
                        <asp:Timer ID="Timer1" runat="server" Interval="1000" OnTick="Timer1_Tick">
                        </asp:Timer>
                    </ContentTemplate>
                </asp:UpdatePanel>

The logic is simple. The timer uses the label which is defaultly set to 60 and decrese it by 1 on every tick which has interval of 1000 miliseconds.Everything works perfectly but unfortunately the timer starts to count down right after I load the page. I want somehow to attach the timer to start when I click the button with ID "schlbtn1".

The timer is enabled by default when created, so you'll need to create it disabled, then manually enable it. You can do that as follows:

In your UpdatePanel (note Enabled is set to false):

<asp:Timer ID="Timer1" runat="server" Enabled="false" Interval="1000" OnTick="Timer1_Tick"></asp:Timer>

Then enable the timer in the click event of your button (schlbtn1_Click):

Timer1.Enabled = true;

This will cause the timer to start disabled, then start when the button is pressed.
