wizard ctrl within modalpopup: how to access the "finish" button? 1

[NuJoizey]

I have an asp.net wizard control which opens in a modal popup. It works nicely for the most part. User clicks a link, and the user can click thru wizard while the background is disabled.

However now I find I have the need to disable the Finish button on the last page of the wizard upon a certain event, but it seems not to be accessible. I can't believe it isn't accessible at all, there MUST be a way, right? So far, everything I try throws a javascript error "Object Reference not set to an instance of an object". If I hit view>source, I can't seem to find the control rendered anywhere.

in my wizard aspx, i have templates defined like so:

<FinishNavigationTemplate>                           
   <asp:Button ID="btnPrevWiz4" runat="server" Text="PreviousX" >
  <asp:Button ID="btnFinishWiz4" runat="server" Text="FinishX" />
  <asp:Button ID="btnCancelWiz4" runat="server" Text="CancelX" />
</FinishNavigationTemplate>

vb code that i tried which doesn't find the control looks like:

'This doesn't work:
'Dim btnFinishWiz4 As Button = Me.wizNewPlacementStep4.FindControl("btnFinishWiz4")

'..and neither does this
Dim btnFinishWiz4 As Button = Me.panNewPlacement2.FindControl("updNewPlacement").FindControl("wizNewPlacement").FindControl("btnFinishWiz4")

'this is what i'm trying to do:  disble the button when certain circumstances exist:
btnFinishWiz4.Enabled = False

Need help! This is a showstopper for me! I think it may have something to do with the fact that the wizard lives on a modalpopupextender control, (am i right?) but danged if I can find how to access it to do what I want!!!!

I pretty sure it has nothing to do with the modal. as a test spike a quick webpage with a simple 2 step wizard. then find the finish button.

You may have to find the finish template, and then find the finish button within the template.

Thanks Jason. You are most trusty. I don't think I could do my job without you.....but maybe someday...... <ha ha>

Anyway, your post was very helpful to me in that it bolstered my resolve to keep searching for the answer, which seems to be:

Dim btnFinishWiz4 As Button = Me.wizNewPlacement.FindControl("FinishNavigationTemplateContainerID$btnFinishWiz4")

which I found in this post:

..and like one of the posters commented, I don't know where the heck I would have ever found it myself.......

they are kind of a pain, and seem to require a lot of coding and esoteric syntaxes. To me there are a lot of things that aren't intuitive, or easy to find out. I waste a lot of time saying to myself "i know there must be a way to do this......but how....."

Are you referring to developing using MVC or something like that?

 

[jmeckley]

exactly mvc with a sensible html engine is great. I use Monorail with aspview (closest to c#) I want to find time to tool around with Spark. that is a wickedly slick html engine.
