I'm gonna be interested in reponses to this one, I see no other alternative to updating the service reference whenever you change the service.

I do take exception to having my method called unprofessional Mad | :mad:

If you can reference an assembly with your service interface and any types you might use. Then you can use the ChannelFactory

ChannelFactory factory = new ChannelFactory<IService>()
IService myService = factory.CreateChannel();
myService.Foo();

the drawback is you don't have any auto generated code so if you need asynchronous calls then you'll have to write that yourself.

If you need the auto generated code, then I suppose you could use svcutil in the post build event of your service project.
eg.

svcutil "http://localhost:1892/IMyService.svc" /out:OutputDir\MyService.cs

This however requires that you have an ISS running with a site that has your service's output directory as it's Content directory.
Also you proporbly have some kind of source control so you might want to add some lines before the above line so that MyService.cs is checked out before svcutil overwrites it.

That's the only two way I know of to avoiding having to update the service reference.

All this b/c the OP does not like the auto generated code. Not a chance, I have no problem using the auto code, I know what it does, I understand how it works and I have absolutely no interest in circumventing the MS methodology.

The only time I can justify chucking this type of auto generated code is if the code is flaky or it needs to be extended for some reason, so far this has not been the case!

I don't see how either of those two methods is circumventing the MS methodology.
When you press Update Service Reference it's svcutil that is being used.

Using the ChannelFactory is what I personally use when I control both the server and the client. My primary reasons for this is; I don't have to update anything(Service reference) and I'm not limited to using DTO's.

While converting a project from using the auto generated proxy to using the ChannelFactory may very well be a waste of time. I do still beleave my other suggestion (using the svcutil) is easy to do and would work.

I work for a defense contractor, and all of our web sites require smartcards in order to access them. To make matters worse, after a given amount of time of inactivity, the user's PIN must be re-entered before you can continue using the web site. We we were contemplating moving our web sites over to Silverlight4, but we're not sure how to proceed given the smartcard requirement.

I know we can use an aspx web site to allow access to a silverlight app, but the inactivity aspect is not so clear. Has anyone here done a silverlight app in a similar environment (US DoD contractor) that's controlled with a smartcard?

Build TreeViewItem dynamically [modified]

6-Aug-11 2:47

We implement a timeout and log the user off if there is no activity through the navigate method. If some poor bastard needs to sit and stare at a single page for more that 20 minutes then thats just tough, they are out of there.

Hi all,

I need to build TreeViewItems dynamically in Silverlight4, C#.net, Visual Studio 2010 Premium.

Currently the TreeView consists of only a lot of TextBlocks, and I need to put a CheckBox in front of each TextBlock dynamically. This has to be done in code-behind, not in the xaml.

I have done a few Google searches, but could not find anything that I could use to guide me to do this.

Please provide me with links to articles/demos/discussions/etc that will help me.
Some code snippits would be appreciated too...

Thanks Cool | :cool:

You should explain what you are trying to do. Telling us you need to dynamically build a UI from the code behind sounds like you are headed down the wrong path. I just wrapped up a customized TreeView that I wrote that does exactly what you are talking about... added checkbox and image support to the stock WPF TreeView. None of my code involves dynamically building the UI from the code behind. Its all in XAML via triggers, etc.

McCombi7-Aug-11 22:29

Done in XAML via triggers?
I have never heard of triggers in XAML.
What is it, and how are they used?
But I guess that's for another thread, huh.
I'll Google it... Thumbs Up | :thumbsup:

Sledge has got it right, if you are using code to create a UI element you are doing it WRONG. Build you template in xaml with a stackpanel containing a checkbox and a textblock, bind them to your data collection. Your data collection may be manipulated from the code but not your UI element.

Thanks for the replies.

Additional Info: The UserControl that contains the TreeView is used on another page too, but NOT with the CheckBox. The functionality there requires the user to actually select the appropriate TreeViewItem. In the new scenario, the TreeView is be populated with exactly the same data is on the other page, but with the additional CheckBox for each TreeViewItem where the user is allowed to select multiple CheckBoxes in the TreeView. My idea was to just add the CheckBox to each TreeViewItem dynamically as each is built, and before it is added to the TreeViewItems collection.

Question: Should I put another grid in my XAML with exactly the same methods etc as for the original TreeView, but with the additional CheckBox as part of the TreeViewItemTemplate?
Then whenever this altered TreeView is needed, I toggle the visibility of the 2 grids in my XAML?
Thanks again for any directional advice and alternative suggestions.

Windows Phone 7, buttons and events when moving your finger

31-Aug-11 2:39

Hi all,

This is how I did it.
I hope it helps someone in the future. Cool | :cool:

Microsoft.Windows.Controls.TreeViewItem treeitem = new Microsoft.Windows.Controls.TreeViewItem();
StackPanel sp = new StackPanel();
sp.Orientation = Orientation.Horizontal;
CheckBox cb = new CheckBox();
sp.Children.Add(cb);
sp.Children.Add(treeitem);

Hallo!

I developed a game for Windows Phone 7 (myStraights).
During the game you are able to enter numbers. I'm not satisfied with the solution I have.

The buttons are simple WPF buttons without
further change. I'm searching for a solution for following problem, maybe someone can help me:

I tried to create a virtual keyboard (but just with numeric values) like
the original virtual keyboard of the Windows Phone 7 (the original keyboard takes up too much space). When a button is pressed and somebody is moving his/her finger to another
button, the button raises the Mouse_Leave event and on the other button the Mouse_Enter event.
On the first button the Mouse_LeftButtonDown event occures. When you're leaving the original
button, the Mouse_LeftButtonUp event doesn't occure on another button when raising the finger, that's okay Smile | :)

What I did: In code I remember which button was the last "Mouse_Enter" button, when leaving the button and leaving the container of the button. Maybe the player wanted to press this button, but this is not for sure. The last position of the finger (observed throw the MouseMove event) is not reliable. I'm searching a method to determine whether the finger was over a button at the time on which the user raised the finger.

Thanks in advance, many greetings,

Thomas

Overiding context menu default style except for textbox contextmenu

All custom context menus are styled using a common control template in the
application resource dictionary which overides the default style. This in turn affects the textbox contextmenu
and gives a distorted (cut, copy, paste) menu options. Is there a way to do except for
the contextmenu style of textbox?

HTML

<ControlTemplate 
  x:Key="{x:Static MenuItem.SubmenuItemTemplateKey}" 
  TargetType="MenuItem">
	<!-- ... -->
</ControlTemplate>

If you give a ControlTemplate a key as you have above, its not applied to anything unless you specifically tell it to use that template. If it doesn't have an x:Key, its applied to everything.

Error: Cannot find governing FrameworkElement for target element

Look into cellstyleselecteor at Telerik, this allows you to manage a cell based on the content, not sure if it can be coerced into managing the content of the cell.

I would ask this in the Telerik support forums, I find them very helpful supporting their products.

Same issue[^] and the work around given here works perfect but has a disadvantage that designers cannot work on the UI part if we move the code to the converter. any alternate?
