stop postback from code behind using c#

Question

I have a button and I want to stop post back whenever someone clicks on that button.

I don't want to use return false like this

  <asp:Button runat="server" Text="Click" OnClick="Unnamed1_Click" OnClientClick="javascript:return false;" />

I want to stop it from code behind.

I want to create a div and some content inside the div , so when ever someone click on that button another div will be created with it's contents, but the problem is when I click the button and a post back happen , it remove the first div and construct the second one and so on

Answer 1

Something you can do is to disable your button after a user click on them it also disable the postback behaviour and prevent future postback, in this way

protected void Unnamed1_Click(object sender, EventArgs e) {
    YourButton.Enabled = false;
}
