OKCancel Messagebox

Hello,
I know that you cannot use MessageBox.show() in asp.net and use the following code to bring up a simple alert messagebox:
System.Web.HttpContext.Current.Response.Write("<SCRIPT LANGUAGE=JavaScript> alert(""Blah"") </SCRIPT>")

I have changed the word 'alert' into 'confirm' and brought up an ok/cancel box (as required) however do not know how to capture the ok or cancel as clicking either button does the same thing.

Can you please tell me how to differentiate between the ok and cancel button being clicked so i can perform the desired event (if ok is clicked) or not (if cancel button is clicked)

Thanks in advance,
Max

function confirmSubmit() {
var doc = document.forms[0];
var msg = "Are you sure you want to submit this data?";
if (confirm(msg)) {
doc.submit();
} else {
// do nothing
} }

<input type=”button” value=”submit” name=”butSubmit” onClick=”confirmSubmit();”>

butSubmit.Attributes.Add("onClick", "return confirmSubmit();")

Use this one, if you hit confirm then it posts, if not it doesn't

Regards,

Aeros

thanks for your fast answer, any chance you might have it in vb/asp.net? am having a few problems converting over. also is document.forms a generic term or do i have to add in a different term?

thanks again,
Max

It has to be client side to display the message and thus your only option for this is javascript.

my apologies, late in the day here :p
finally, is there anything i can do to make this work with an asp button instead of a html one?
when i run my program it creates a compiler error that confirmSubmit is not a member of the class. boo!

<asp:Button id="btnSave" runat="server" Width="120px" Text="Save"></asp:Button>

in Page_Load
{
btnSave.Attributes.Add("onClick", "return confirmSubmit();")
}

if returns false...that is if user clicks cancel...

the btnSave_click will never fire...

if they say ok the btnSave_click fires...

good luck

ok change the javascript function to

function confirmsubmit()
            {
            if (confirm("Are you sure you want to submit?")==true)
            return true;
            else
            return false;
            }

it should work fine now

Same thing, different approch:

Just add following line in your Page_Load
--------------------------------------------------------------------------------------------------------
Button1.Attributes.Add("OnClick", "return confirm('Are you sure?');");
--------------------------------------------------------------------------------------------------------
