Use confirm messagebox to show 'yes/no' option in that popup, and do different work based on click either yes or no.
eg

protected void Button1_Click(object sender, EventArgs e)
    {
        ClientScriptManager CSM = Page.ClientScript;
        if (!ReturnValue())
        {
            string strconfirm = "<script>if(!window.confirm('Are you sure?')){window.location.href='Default.aspx'}</script>";
            CSM.RegisterClientScriptBlock(this.GetType(), "Confirm", strconfirm, false);
        }
    }
    bool ReturnValue()
    {
        return false;
    }

You can store the value of confirm_proceed() in an asp:HiddenField

You can modify your script as follows:

<script type = "text/javascript" language = "javascript">
     function confirm_proceed()
     {
       var hiddenField = document.getElementById('hiddenFieldId');
 
       if (confirm("Are you sure you want to proceed?")==true)
       {
         hiddenField.value = 'true';
         return true;
       }
       else
       {
         hiddenField.value = 'false';
         return false;
       }
     }
</script>

You can now access first the hidden field's value in your Button2_Click event.

or try this simple

you can also do it like below one

hi

For true Javascript standard it is not possible. This will only work on 32 bit Windows and only on IE. On Firefox it will not show Yes/No prompt.
