how to give prompt message & after that redirecting page to another in button click event in asp.net

Question

Hi I have one submit button to submit the page. When i click on submit button then it should give prompt message like "are you sure to submit that page really" if yes then it should redirect the another page. I used code as follows:

RegisterStartupScript("myAlert", "<script>alert('Are you sure about to submit the test?')</script>");
Response.Redirect("Result.aspx");

But its directly redirecting the page without promting to user with message. How its possible? Asp.net c#

Answer 1

you can do like..

<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="javascript:return 
confirm('Are you sure about to submit the test?');" OnClick="Button1_Click" />

and then in code behind...

protected void Button1_Click(object sender, EventArgs e)
{
    Response.Redirect("Result.aspx");
}

There's a modalpopup in Ajax Control Toolkit, maybe that would work for you?

Dont remember the exact syntax but you need to capture the clicked value and based on that you can do either a return true or a return false. True will submit the page
