How to do both simultaneously?

i am working on an C# application..

let me explain

I want to let user to download an a book using my given link in button_2. but the condition is that

user can only click the button when he/she shares this application on whatsapp by clicking on Button_1

for that I did this code.

protected void Button1_Click(object sender, EventArgs e)

{

Response.Redirect("https://api.whatsapp.com/send?text=This app is giving Unlimited Paytm cash to celebrate Independence go and download the app for free http://student-cell.com/mybook");

Button2.Enabled = true;

}

protected void Button2_Click(object sender, EventArgs e)

{

Response.Redirect("http://mybook-studg.com");

}

If a user tries to click the button_2 without clicking on Button_1 it can not happen because I went to Button_2 property and did Enabled is False.

Please share me the right code.

Whatever you did looks good but there are alternates like:
- Put only one button and club both the codes(both whatsapp and download)
- or if you want two different event handlers like you did then you can use some boolean property which will be set only when whatsapp part is done and based on the state of this property, you cna handle enablign and disabling.
