I’ve just started to build the UI for a quite big WPF-application, and the skeleton of the program will be built with tabs to separate each section of the program. So my question is: what is a proper way to manage all the code inside the TabItem-tags? There will be a lot of UI-code inside the tags (and a lot of code behind as well) so I’m wondering if I can build the UI and the code behind for each TabItem in a separate file and then include the file inside the TabItems?
I’ve been thinking a lot about WPF-pages, but I don’t know how to load them inside a TabItem (I don't even know if it's possibel). But that’s just me thinking, what’s your opinions?
My main file will look something like this:
<StackPanel>
<TabControl TabStripPlacement="Top">
<TabItem Header="Tab1" IsSelected="True">
<!-- Include Tab1 info -->
</TabItem>
<TabItem Header="Tab2">
<!-- Include Tab2 info-->
</TabItem>
<TabItem Header="Tab3">
<!-- Include Tab3 info -->
</TabItem>
</TabControl>
</StackPanel>
Thanks!

I'm not sure about pages, but UserControls should work. If you are going to have several tabs that all have significant logic, I would recommend doing that to make it easier to manage.

Can we use ASP.NET website inside the Silverlight application?

No. Why do you want to use ASP.NET website inside Silverlight?
|
|
|
|
|
What do you mean by "Can we use it?"
Are you asking if you can reference asp.net objects from a silverlight application?
Are you asking if you can display/run asp.net pages within a silverlight control?
Are you asking if Silverlight application can host an asp.net site?

I had had a similar question a little while ago. i wanted to write the majority of the application in Silverlight but then wanted the ability to display aspx pages in a browser control within the Silverlight app.
I stopped the project before I really needed it so I never got far towards figuring it out really but I am still interested...

Well... let's say a Silverlight app must live inside a web page (e.g. an ASP .net web project).
How to integrate both applications?
--> ASP .net using WCF services inheriting the ASP .net context (session).
--> using the bridge enabled that let Silverlight access properites and method in the javascript and the other way around (you can call from javascript a silverlight method).

I have been using the MVVM pattern extensively to build a UI (as in the great samples "WPF Apps With The Model-View-ViewModel Design Pattern"[^] and "Creating an Internationalized Wizard in WPF" [^]. This is a great technique for UI development, and I thank Josh Smith and Karl Shifflett for their postings and assistance in this area.
While I have now got most of this working really well, I have hit a problem that I can't figure out how to solve in xaml or with data binding. I have a ListBox which I can add items to, but as the number of items exceeds the size of the ListBox, the items added at the bottom scroll out of view... I want to have the ListBox automatically scroll to display the last item. Can anyone tell me how to do this in xaml?
I have reviewed several posts regarding use of the ScrollIntoView method, but I do not know how to access this from xaml (I think it may not be possible as its a method). As this is using the MVVM pattern, there is no way (that I am aware of) to access the ListBox instance from the code, to be able to call ScrollIntoView.
Another solution would be to scroll to item n in xaml, which would be fine because I could then data bind to n. However I also have not been able to find a way to control the scrolling in xaml.
I'm realy surprised there seems to be no easy way to do this in xaml.
Any help would be greatly appreciated.
Thanks,
Tim

Hey guys,
I'm creating a control in blend and I'm having some trouble understanding how I would accomplish a certain task.
The idea is I put a textblock on a form and then during runtime, this textblock's text must change based upon 4 different buttons that are pushed within the same control.
The problem is, I'm new to WPF and Blend - and I am unsure if this is possible.
The only alternative is I add a label in place of the textblock and change that text programatically(using visual studio code) - is this the preferred method or is there a way to bind the textblock.text to one of the selected buttons and have it change dynamically upon the selected button?
Thanks in advance,
Smithy.

In some way shape or form you will have to do some code behind (visual studio) in order to accomplish what you want. I do not believe it is possible for one xaml property to be binded to one of 4 different xaml controls. You will have to add some logic in order to accomplish what you want.

Hi all,
I am trying to practice and create a simple data template for a simple class I wrote.
CLR:
public class Customer
{
public string CustomerName
{
get { return mCustomerName; }
set { mCustomerName = value; }
}
public List<string> RentedBooks
{
get { return mRentedBooks; }
set { mRentedBooks = value; }
}
public string mCustomerName;
public List<string> mRentedBooks;
}
</string></string>
My Questions:
1. Do I have to create a property for CustomerName? I didn't get it to work with a public member, only with an explicit property declaration.
2. How do I get the list of strings to be displayed using a listbox?
Thanks all...

Yes[^]
pym wrote: 2. How do I get the list of strings to be displayed using a listbox?
like this,
mylist.ItemsSource = new List<string>() { "I", "LOVE", "WPF"};</string>
mylist is a ListView in XAML.I am setting the ItemsSource of mylist in the Window load event(code behind).

Thanks for your answer!
Now I need something more complicated (or not)...
I want to display the books the customer has rented.
Mark him those that he needs to return (rent date condition).
Let him select what books to return and get the selected items in the code behind (listbox is in SelectionMode="Multiple").
Any ideas for that one?
Thanks!

Not complicated at all. Try, and if you get stuck the forum will help you out.

I want to create a data template for a Book class (Name, Description, Genre etc.)
I know how to bind and template this but I am still missing a piece of the puzzle.
What I mean is Name and Description have one string value and my template binds perfectly to the fields in the class.
Problem I face is that Genre has some meta data behind it (Drama, Comedy, Horror etc.)
I created a Label and TextBlock for both Name and Description.
A ListBox for the Genres.
My Question:
How do I template the class' instance to display the whole list (in a list box for instance) while displaying the current genres selected ?
One data structure holds the genres available and the Book instance holds the specific genres.
Hope you understand what I am trying to say.
Thanks!

I want to add some custom properties as well as the existing properties should remain same in the controls.
Some of the controls can have the extended properties, but some controls like Textblock are sealed so can not be able to inherit other controls from the existing control.
Anybody have any idea that how can we extend the exisiting silverlight control's properties?
Thanks in advance...
|

If you want to extend an existing control, I'd look to use an Attached Property.
|

I have tried it with two ways:
1. Inheriting from teh existing control and add our custom property to it, include it in the xaml page as a new namespace and use it.
But it is not working in the case when the control class is sealed for example Textblock....
2. Created a wrapper class having the TextBlock and my custom property.Initialize the Textblock in constructor,include it in the xaml page as a new namespace and use it.
But it is also not working in the case when we give the "x:name" to that control...
No other idea how to do?

I'm not sure how many different ways to say this. Perhaps I need to shout here. USE ATTACHED PROPERTIES. That's it - full stop, finito. That's the WPF/Silverlight way of doing things.
There are very few instances where you need to subclass existing controls.
