Server Mappath: Server Side Confirmation pop-up...

Dan,

You're just thinking about it too hard! :)

Try this:

WebControlButton.Attributes.Add("onClick", "javascript:if(!confirm('Do you
wish to complete this order?')) return false;")

Now if the confirmation goes through the WebControlButton's click event
server side will be fired and your server side code can all go there.

If the confirmation's cancel button is clicked note that the javascript
function returns false. The form will not be posted back in that case.

Is this what you want?

Only I'm getting and object doesn't exist error on this block in the HTML,
the highlight in question sort of starts at the "a" in false and goes
through to the "d" in __doPostBack... so I'm not sure which one it's
complaining about.

onclick="javascript:if(!confirm('Do you wish to complete this order?')) {
return false; } __doPostBack('btnComplete','')"

Thanks.

Dan,

Did you add the do post back stuff yourself?

I run the code I gave you in my codebehind page's page load and it's
produced in the html sent to the client like this:

<input type="submit" name="Button1" value="Button" id="Button1"
onClick="javascript:if(!confirm('Do you wish to complete this order?'))
return false;" style="Z-INDEX: 101; LEFT: 8px; POSITION: absolute; TOP: 8px"
/
Where is the doPostBack routine of yours coming from?

As long as you're using a asp.net button then that button is associated with
a server side event.

It would look like this:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click

'--Put your code here

End Sub

I've got an confirmation box, which will have to be launched client side.
I then need some server side code to be launched if there is a "yes" click
on the confirmation screen...

is this possible?

you either have a server side event handler, or a onClick event handler in
the client... this is what's causing me the problem.

the post back stuff is a result of me adding a server side handler for the
button...
if i don't have an event handler, then how can i get a server side method to
run after this client side event?

You'll have to add an event handler.

Thanks for your patience, you must think i'm thick!!!

to clarify... I add

WebControlButton.Attributes.Add("onClick",
"javascript:if(!confirm('Do you wish to complete this order?')) return
false;")

to the Page_Load method...
I also double click on the button then, to write my server side stuff,
getting this :-

Public Sub WebControlButton_ServerClick(ByVal obj As Object, ByVal e
As System.EventArgs) Handles btnRelease.ServerClick

...some server side stuff

End Sub

so this then executes the javascript, then if the user clicks okay,
processes my WebControlButton_ServerClick method?

but i get an object doesn't exist error when i do this,
onclick="javascript:if(!confirm('Do you wish to complete this
order?')) { return false; } __doPostBack('btnComplete','')"

on the doPostBack which the compiler adds when the page is processed.

It took me quite a while to get the hang of this so, no, I don't think your
thick! :)

When I use this code there is no __DoPostBack

I notice that the __DoPostBack is trying to fire a different button,
btnComplete...

Does this button exist? If not that is the cause of the object doesn't exist
error.

If it does exist try attaching the confirmation to the btnComplete Button
instead:

btnComplete.Attributes.Add("onClick", "javascript:if(!confirm('Do you wish
to complete this order?')) return false;")

the html for the button in question is:

<INPUT id=btnComplete type=button value=Complete name=btnComplete
RUNAT="server"
the aspx.vb Page_Load code is this:

btnComplete.Attributes.Add("onclick", "javascript:if(!confirm('Do you
wish to complete this order?')) return false;")

the event handler looks like this:

Private Sub btnComplete_ServerClick(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles btnComplete.ServerClick
Dim i = 0 ' break point here so i know it executes
End Sub

but i get this error...

<input language="javascript" onclick="javascript:if(!confirm('Do you
wish to complete this order?')) return false;
__doPostBack('btnComplete','')" name="btnComplete" id="btnComplete"
type="button" value="Complete" /
the stupid thing is that btnComplete is only defined after it's used as a
parameter in the postback method... how in the earth did that happen? You'll
notice the HTML for my declaration puts the ID right at the front.

Hmm... we get closer to the solution though.

Thanks again.
