Prevent Button Double Click ASP.NET Code Behind

Disable ASP.NET Button after click to prevent the double click and change button text to Loading/Please Wait.

Design :

<asp:Button ID="Button1" runat="server" Text="Save" onclick="Button1_Click" />

Code Behind :

//Here javascript added to the button at page load.

protected void Page_Load(object sender, EventArgs e)

    {

        try

        {

            string strProcessScript = "this.value='Processing...';this.disabled=true;";

            Button1.Attributes.Add("onclick", strProcessScript + ClientScript.GetPostBackEventReference(Button1, "").ToString());

        }

        catch { }

    }

//After Button click method wait for 5 Second to check the result.

protected void Button1_Click(object sender, EventArgs e)

    {

       

                Thread.Sleep(5000);

   

    }


Then check you result.
