Re: Is there a FolderBrowserDialog in WPF ?

11-Nov-08 7:21

The link I posted above (in my first reply to this thread) shows
the use of OpenFileDialog as a folder browser. Look in the blog
responses Smile | :)

I tested it - it works, I just didn't like it....a real folder picker
is better IMO.

VS 2008 SP1 XAML Designer Problem Workaround

11-Nov-08 15:13

You're welcome.

I've added the folder browser message callback handler and the
following initialization properties and associated functionality:

public string SelectedFolder { get; protected set; }    // Tracked in BrowseEventHandler() as user changes selection
public string InitialFolder { get; set; }               // Sets the initially selected folder
public string InitialExpandedFolder { get; set; }       // If set, overrides InitialFolder (InitialExpandedFolder will be selected)
public string OKButtonText { get; set; }                // Sets the text that is displayed on the dialog box's OK button.

If you can use the new code, send me an email here and I'll send it
in a reply.

Cheers,
Mark

Re: VS 2008 SP1 XAML Designer Problem Workaround

10-Nov-08 4:27

I was mentioning to Pete a couple weeks ago how I
often have problems working with XAML in Visual Studio
which kept me kind of discouraged about using it, and the
wonderful add-on tools available from him and Karl.

This morning, after a couple weeks of error-free development
and really getting into the VS designer (over Blend), again I
couldn't work with any XAML files. Visual Studio crashed before
I got through my first cup of coffee.

Time to report this to MS. It took about 30 seconds to find the
already-filed bug report (don't know why I couldn't find it months
ago...wrong keywords I guess).

Here it is:

WPF Designer fails to load in VS.NET 2008 SP1 (RTM)[^]

The workaround fixed me instantly. I never imagined setting the startup
project to a Win32 or MFC project would be associated with the XAML designer.
I never made that association while I was working - it just seemed random.

Maybe this will help someone else (or maybe I'm the only one that still works
with native projects) Smile | :)

Cheers,
Mark

Good catch Mark, and what a weird issue. Nice one.

BTW - there's a new MoXAML available here[^]. Big Grin | :-D

I think you mean you want to load loose XAML files as resource dictionaries ... if so ... look at this:

Data Binding In Custom WPF control

Hi All,

I have a custom WPF control (say X). I have a text box(say Y) in X. I will be placing X in a System.Windows.Window object (say Z). Now I want the text in Y to be based(bound to) on a string/int value in X. Now this value of the string/int in X will be based on some value in Z. Hope Iam clear. How can I use data binding to achieve the same? Any help would be highly appreciated.

aspx page inside Silverlight..?

I have a silverlight application, and I want to open an aspx page inside the Silverlight and to interact between them.

Does anyone knows if there is any aspx box container in Silverlight?

Got a partial solution of the problem:

If we use the user control i.e. the .ascx file in the xaml page
we can do it like

1. REgister the usercontrol with following tag in

xmlns:MyUserControl="clr-namespace:SilverlightAppWeb"

where SilverlightAppWeb is the namespace of the .ascx user control

2. Use it anywhere with tag

<MyUserControl:Servicecontent/>

where Servicecontent is the class name.

This was successful for calling xaml file, i.e. xaml usercontrol.

But giving following error with .ascx file:

AG_E_PARSER_BAD_TYPE [Line....]
where the line is <MyUserControl:Servicecontent/> when .ascx is used.

And shows contents when the reference of xaml page is given....

Further let's try....

Short of purchasing[^] a commercial solution there's no easy way to accomplish this (well there is one, but it's a hack). One common way of doing this (the hack way) is to float a div over Silverlight to make it appear that this is inside the actual control.

wpf - nested binding expression?

I have a menuitem inside GridViewColumn.HeaderTemplate

that binds a
CommandParameter=”{Binding RelativeSource={RelativeSource AncestorType=ContextMenu}, Path=PlacementTarget}”

PlacementTarget puts me at a grid that forms the header datatemplate of my GridViewColumn.

what would be the binding expression to continue this up to finally bind GridViewColumn to the commandparameter?

I want to be able to walk up the dom using nested binding expression... anyone know how to do this?

WCF authentication

Hey guys,
I have a WCF data service that works well with an Internet application I developed (using Forms authentication). Now I'm trying to create a WPF desktop application that uses this same data service and does its own custom authentication. The problem is my WCF data service always sees Membership.GetUser() as null. I've tried calling Membership.ValidateUser() within both the WPF application and the WCF data service with no luck. What am I missing, what am I doing wrong?

Thank you,
David

Contact _contact = new Contact();
ContactViewModel model = new ContactViewModel(_contact);
ContactWindow w = new ContactWindow();
w.Owner = this.View;
model.View = w;
w.Model = model;
w.DataContext = model;
if (w.ShowDialog() == true)
ContactList.Add(_contact);
this.View.Focus();}

I got a poor knowledge so i fall down in stupid error losing so much time to understand and after i get confuse so i try to ask help to make me understand how i can work out this error..

Change these lines

if (w.ShowDialog() == true)
ContactList.Add(_contact);

if (w.ShowDialog() == true)
{
  if (ContactList == null)
    ContactList = new List<Contact>();
  ContactList.Add(_contact);
}

HI Pete,
thanks to reply me,
i changed there lines:

if (w.ShowDialog() == true)
ContactList.Add(_contact);

to

if (w.ShowDialog() == true)
{
if (ContactList == null)
ContactList = new BindingList<contact>();
ContactList.Add(_contact); }

because it doesn't allow me to insert List<> so i insert BindingList <t>...
after i will debug and see what happen..
Thanks again.
i wish you happy work.
See you later
