It's done. I've pushed Cocktail 0.7.1 and the corresponding CocktailContrib 1.0.9 to NuGet. ]]> Fri, 13 Jul 2012 12:51:24 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=3398&PID=14018#14018 DialogManager closing problems : Thanks.

Thanks.   If you could, that would be really helpful.  We don't have a very good workaround.]]> Fri, 13 Jul 2012 07:06:50 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=3398&PID=14015#14015 DialogManager closing problems : That is a bug.

That is a bug. I've checked in a fix. Unfortunately, it just missed the 0.7 release I pushed out this morning. I can push out a 0.7.1 NuGet package with the fix if desired.]]> Thu, 12 Jul 2012 16:36:18 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=3398&PID=14009#14009 DialogManager closing problems : We have a situation where... http://www.ideablade.com/forum/forum_posts.asp?TID=3398&PID=14007#14007 Author: JChris

We have a situation where we:
yield return DialogManager.ShowDialogAsync(vm, new List<DialogResult>() { DialogResult.Cancel });
//Check vn properties and do more stuff...
When the DialogResult.OkCancel buttons are shown, and the Ok button clicked, all works as expected, however when we do not show the DialogResult.OkCancel button, but only the Cancel (as above), and then use our own button to handle Ok... as in:
this.DialogHost().TryClose(DialogResult.Ok);
the next iteration block never fires. It seems like TryClose of the DialogHost() does not honor the DialogResult passed to it.
Thanks for your help

I'm adding a TryClose method to the IDialogHost interface, so you'll be able to call this.DialogHost().TryClose(DialogResult.Ok).
 
I'm planning to officially release Cocktail v0.6 on May 2 together with DevForce 6.1.7. I believe we are still on track for the DF 6.1.7 release.

Here is what I tried from the child vm:

((Screen)(this.Parent)).TryClose();

The problem that I had is that the _dialogButton in the DialogHostBase is null so when it enters the canclose function it callsback with false: 

 public override void CanClose(Action<bool> callback)
        {
            try
            {
                if (_dialogButton != null)
                {
                    base.CanClose(callback);
                    return;
                }

                if (_cancelButton != null)
                {
                    DialogButton button = _dialogButtons.FirstOrDefault(b => b.Value.Equals(_cancelButton));
                    if (button == null || !button.Enabled)
                        return;
                    DialogResult = button.Value;
                    base.CanClose(callback);
                    return;
                }

                callback(false);
            }
            finally 
            {
                _dialogButton = null;
            }
        }

What I ended up doing was casting the parent as a DialogHostBase and then calling the Close function since the close function sets up the _dialogButton. Here is my new code in the child vm:
var parent = ((DialogHostBase)(this.Parent)); parent.Close(parent.DialogButtons.First());
Since I know that I only have one "OK" button I am just calling first(). It works great unless you can think of a way to make it easier.

Thanks. Looking back, that should have been obvious. Your help is much appreciated. ]]> Tue, 24 Apr 2012 14:09:18 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=3398&PID=13406#13406 DialogManager closing problems : Missed this post somehow.... http://www.ideablade.com/forum/forum_posts.asp?TID=3398&PID=13405#13405 Author: mgood

Missed this post somehow. If your VM implements IChild, which it automatically does if you extend from Screen or Conductor, you have a Parent property. The parent in this case is the ChildWindow's VM. Just cast it to Screen and call TryClose on it.]]> Tue, 24 Apr 2012 14:04:44 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=3398&PID=13405#13405 DialogManager closing problems : Bump :) We have a dialog that... http://www.ideablade.com/forum/forum_posts.asp?TID=3398&PID=13403#13403 Author: JohnBloom

Bump :) We have a dialog that needs to be able to close the parent VM. It gives the user a list of options and as soon as they click an option it needs to close. Speed is the key for this dialog so we would like to avoid the user having to hit enter. Everything about the dialog works with the new stuff except we lost the ability to call TryClose() on the Manager's VM.]]> Tue, 24 Apr 2012 12:57:40 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=3398&PID=13403#13403 DialogManager closing problems : We have a dialog thatneeds... http://www.ideablade.com/forum/forum_posts.asp?TID=3398&PID=13351#13351 Author: JohnBloom

We have a dialog that needs to close when the user clicks something other than the "Ok" or "Cancel" buttons. Calling TryClose() only closes the vm and not the childwindow.  Is there any way that the child window can close itself?]]> Thu, 19 Apr 2012 08:34:15 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=3398&PID=13351#13351
