As XAML is just XML, you could write it out using the XML features of .NET and then compile it/load it using the XamlReader class.

I want to create datetime, time and duration control...
I have created the datecontrol by using datepicker available in Silverlight....
Do we have any existing controls available in Silverlight 2.0 so that I can make datetime, time and duration controls...?
Or have to extend some controls to get above controls?
Can anybody have some code / hyperlinks from where I can get the idea?

I have ListBox in test.xaml:
<grid>
<listbox margin="12,28,0,0" name="ListBox1" horizontalalignment="Left" width="77" height="100" verticalalignment="Top">;
;
And in the test.xaml.cs file, I initialized the ListBox as
for (int i=1; i<=50; i++)
{
ListBox1.Items.Add("Item" + i);
}
Now I want to set a "HelpText" AutomationProperty to each of the ListItems. How do I do it?
I heard it could be done through Binding? Can some one provide me the required info?
Thanks.

Since the Silverlight XAML designer is only partially implemented in VS,
it can be "challenging" to find the offending code or markup

Hi.
I have a big image ( like a map ).
I wanna show it in an image (in WPF) as when user do MouseDown on it , it can move map coordinates .
Something like Google map.
Could you guide me how I can do it ?
Thanks

A popular way to deal with images that are too large to fit all at once
into a practical amount RAM and/or transferred across a network in a reasonable
amount of time is to deal with the image in parts, or "tiles".
Displaying a single tile is relatively easy...handling mouse events is relatively easy...
Designing a system to work with tiles and keep track of them is the majority of the
work.
What kind of guidance are you looking for? Do you have a more specific part of the given
problem that you are struggling with?

I'm green in these subjects (tiles and move image with mouse events).
Could you post a references about them ?

By "tile", I mean a rectangular (usually) portion of a larger image.
For example, I work with large images (larger than 20000 pixel dimensions) divided
into tiles 256x256 and/or 512x512 pixels.
How you load, cache, and render the tiles depends on your requirements.
Maybe start with the fundamentals:
WPF Fundamentals[^]
Input Overview[^]
WPF: Images[^]
Of course, if your entire image fits in memory, you could simply use an Image control

Hi,
I am creating a chat program in WPF based on the one I made in WinForms,
to give it an edge and a cool new look.
As part of the program, when the user logs in, it displays a custom
welcome message with the user's name in it. I used the 'modified' tag in
VB WinForms to do this.
The code I am using for this operation is:
Dim name As String = ""
If TextBox1.Modified Then
name &= TextBox1.Text
End If
If name <> "" Then
Label3.Text = ("Welcome " & name)
MsgBox("Welcome " & name)
End If
I am wondering if anyone
knows what the equivalent is in WPF as I have no idea. I would also like to know if you
can put a WebBrowser control on a form in WPF. Any responses would be
greatly appreciated. 
Dloog!

What you could do (and I'd recommend this) is use two way databinding. That way, you don't have to write code to check for modified flags or the like. First of all, you should write a class that implements the interface INotifyPropertyChanged like so:
public class Login : INotifyPropertyChanged
{
private string _name;
public string Name
{
get { return _name; }
set
{
if (_name != value)
{
_name = value;
Changed("Name");
}
}
public event PropertyChangedEventHandler;
protected virtual void Changed(string propertyName)
{
PropertyChangedEventHandler handler = PropertyChanged;
if (handler != null)
{
handler(this, new PropertyChangedEventArgs(propertyName));
}
}
}
}Then, in your XAML, you'd bind the textbox and the label to the same property
:<TextBox Text="{Binding Path=Name, Mode=TwoWay}" MaxLength="10" />
<Label Text="{Binding Path=Name, Mode=TwoWay}" />Bind this object to the datacontext of your window, using this.DataContext = new Login(); in the window class (you may want to do this immediately after you the call to InitializeComponent();. Now, when you change a value in the textbox, the label updates automatically.

One could still go wild with an attached behaviour in order to mimic the WinForms functionality, but with WPF, it really isn't necessary anymore. But you gotta love the flexibility of the platform

Oops. I'll have to sort that out.

Damn straight. Attached functionality is one of the reasons that the Tag property is no longer necessary.

Sorted - take a look under the Meta link. I've moved it to the top from the bottom of the sidebar.

It was there the whole time, wasn't it? It's surprising how the brain even filters information ("do not interpret entries in the meta section because there's the admin stuff") even if you don't want it to. I honestly never noticed that there's an additional feed link although my blog runs on WP, too 
In case I'm not the only one with that particular problem - an RSS link in the top area along with a shiny orangy RSS icon might help to get you some additional readers. Maybe not the brightest ones
