You could deploy it using ClickOnce, which would download the relevant framework, or you could add the framework in as a required resource into the installer for your project, or you could supply the link for the user to download and install the framework.

Hi,
I selected framework as a required resource. But even then the error appears.I created setup. but if we run it using the setup the UI gets collapsed.

I'm not sure what that means. If you're having trouble with the deployment, use ClickOnce and let the user download your application from a central server.

Install .net - I mean if it's a .net application then you're going to need .net installed

To run applications developed in WPF, u need to install the .NET framework which is available for download. U must download and install it on the target computer to make your application run.

I tried with this code to wite an XML file to the server (local host). But that VWDExpress doesn't see the XmlWriterSettings and XmlWriter. I think I am using the wrong references. Can anybody tell me in what reference XmlWriterSettings and XmlWriter can be found?
Thanks,

PS, If anybody can get me a sample project I would appreciate it.

I just discovered that I hadn't included a using System.Xml; line in the header.
But where do you specify the filename of the xml-file you are trying to save?

Why doesn't this work? There is no test.xml file created and when the program tries to open the xml file (which I manually placed) I get an error message saying 'line 1 character 1 illegal character'.
Is there anybody who could tell me how to get this to work?
Thanks,
Ranger.

The XmlWriter you are using should be writing the XML to the StringBuilder,
not to a file.
In Silverlight 2, the only access you have to the user's local hard disk
is using Isolated Storage:

Probably because your StringBuilder has "test.xml" at the beginning of its contents,
which isn't valid XML.

Ok, I see...
What I would want to do is write an XML file with data to the server where the Silverlight application is situated.
Is this possible at all? Or is the only option Isolated Storage on the computer of the person who is viewing the Silverlight application?
Thanks!
Ranger.

Silverlight runs entirely on the client side.
To write to a server, you'll need to send it to the server.
Here's some info on ways to do that:

Thanks ABitSmart And Pete for your answers. I am trying to use RoutedEvent correctly this time. But the RoutingStrategy doesn't work.
MyButtonSimple class has a RoutedEvent which RoutingStrategy is Tunnel.
public class MyButtonSimple: Button
{
// Create a custom routed event by first registering a RoutedEventID
// This event uses the bubbling routing strategy
public static readonly RoutedEvent TapEvent = EventManager.RegisterRoutedEvent(
"Tap", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(MyButtonSimple));
// Provide CLR accessors for the event
public event RoutedEventHandler Tap
{
add { AddHandler(TapEvent, value); }
remove { RemoveHandler(TapEvent, value); }
}
public MyButtonSimple()
{
this.Tap += new RoutedEventHandler(MyButtonSimple_Tap);
}
//Handle the TapEvent
void MyButtonSimple_Tap(object sender, RoutedEventArgs e)
{
Debug.WriteLine("Tag:"+this.Tag.ToString());
}
}
Then I have a Window1 to test MyButtonSimple like this
<Window x:Class="WpfApplication1.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfApplication1"
Width="300"
Height="300">
<local:MyButtonSimple Width="80"
Height="80"
Tag="OuterButton">
<Canvas Width="60"
Height="60"
PreviewMouseDown="Canvas_PreviewMouseDown">
<local:MyButtonSimple Width="20"
Height="20"
Tag="InnerButton"/>
</Canvas>
</local:MyButtonSimple>
</Window>
private void Canvas_PreviewMouseDown(object sender, MouseButtonEventArgs e)
{
RoutedEventArgs newEventArgs = new RoutedEventArgs(MyButtonSimple.TagEvent);
(sender as Canvas).RaiseEvent(newEventArgs);
}
Well, just as my anticipation, the output window printed "OutterButton". But when I change the RoutingStrategy to RoutingStrategy.Tunnel, which I anticipate to raise the InnerButton ,the output window still printed "OutterButton".
Is it against the routed mechanism? And Many ways I've tried since then(such as raise the event in Canvas_MouseDown), it still printed "OutterButton". And what I wanna see is "InnerButton".
Am I doing wrong angain or the RoutingStrategy doesn't work this way?

No, it works.
When you set it as bubbling, it starts from itself and ends at the root.
When you set it as Tunneling, it starts from the root and ends at itself.
mildred-frontfree wrote: (sender as Canvas).RaiseEvent(newEventArgs);
Remember, you are raising the event from the Canvas.
In your case, when you set it as bubble, it started from Canvas and searched upto the root. It only found OuterButton, which is correct.
When you set it tunneling, it started from the root. It found Outerbutton fired event for it. Continued upto the Canvas and never found anymore MyButtonSimple.
If instead you had raised it from InnerButton, you would have got your desired output.
Try this,
<local:MyButtonSimple Width="100" Height="100" Tag="OuterButton">
<Canvas Width="80" Height="80">
<local:MyButtonSimple Width="60" Height="60" Tag="InnerButton">
<Canvas Width="40" Height="40" PreviewMouseDown="Canvas_PreviewMouseDown">
<local:MyButtonSimple Width="20" Height="20" Tag="MoreInnerButton"/>
</Canvas>
</local:MyButtonSimple>
</Canvas>
</local:MyButtonSimple>
When you set the event as Bubbling, it will print InnerButton and then OuterButton.
When you set the event as Tunneling, it will print OuterButton and then InnerButton.

Yes, Indeed, it works very well. I misunderstand the Tunneling mechanism, I thought it route down to mySimpleButton form the OriginalSource not the Root Element. RoutedEvent is really flexible. Thanks for your suggestion!

Hi,
I'm using Silverlight.createObject() and createFromXaml() Javascript functions to render some XAML files. This works great but the Button element not. I can make some TextBlock, TextBox, Grid, StackPanel, and more controls, but the simple Button I can't be added to my dynamic XAML. Someone could explain me this?
My code is something like this:
<pre>
Javascript
function embedSilverlight(parentElement, pluginId, userContext)
{
return Silverlight.createObject("sample.xaml",
parentElement, pluginId,
{
width: 500, background: "white", alt: 'No Silverlight',
version:"2.0.31005.0", autoUpgrade:true
},
{
onError: onSLError,
onLoad: function(plugIn, userContext, sender)
{
var xamlFragment = $(parentElement.id + '_xaml').get('html');
xamlFragment = xamlFragment.substr(12, xamlFragment.length - 18);
var child = plugIn.content.createFromXaml(xamlFragment, false);
sender.children.add(child);
}
},
"", userContext);
}
function onSLError(sender, args)
{
// Display error message.
}
sample.xaml
<canvas xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation">
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Name="slView">
</canvas>
And the content are snippets like:
<grid xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" width="500"><grid.rowdefinitions><rowdefinition height="20" /><rowdefinition height="*" /><rowdefinition height="20" /></grid.rowdefinitions><textblock grid.row="0">Form Silverlight</textblock><stackpanel grid.row="1"><grid margin="4, 4, 4, 4"><grid.columndefinitions><columndefinition width="100" /><columndefinition width="*" /><columndefinition width="50" /></grid.columndefinitions><textblock grid.column="0">Name</textblock><textbox grid.column="1" width="200" text="Simio" /><textblock grid.column="2">*</textblock></grid><grid margin="4, 4, 4, 4"><grid.columndefinitions><columndefinition width="100" /><columndefinition width="*" /><columndefinition width="50" /></grid.columndefinitions><textblock grid.column="0">Email</textblock><textbox grid.column="1" width="200" text="" /><textblock grid.column="2">*</textblock></grid></stackpanel><stackpanel orientation="Horizontal" background="Silver" grid.row="2"><rectangle stroke="White" strokethickness="1" /><textblock>Sign up</textblock></stackpanel></grid>

Yes, sorry, but the point is when I try to add a child Button in my canvas, I can't do it. It returns me a Javascript error saying the Button element is unknown.

I am using .Net 3.5 and WPF.
I've got a list box that needs to draw text in one of three ways, depending on some criteria. In the process of trying to make this work (which it still doesn't), I've got this question:
When I do this:
private void listboxWords_LayoutUpdated(object sender, EventArgs e)
{
ListBox listbox = sender as ListBox;
}
...both of the method parameters are null. Why?

The way to owner draw is to have a number of derived classes for styles and then to set the style in XAML. As for your event, I have no idea, but I do believe that's the wrong time to be trying to change how things look.

Well, I googled the helll out of it before posting my question, and that's how everyone seems to be doing it. I hate WPF.

LayoutUpdated is a static event. It is fired on layout change of any element in the element tree. It's by design that no parameters are passed to it. That's how it is. Link[^]
For your case, you might want you have a trigger (if the criteria is a property value) or an ItemTemplateSelector[^] (if the criteria is a type)

Then why the frak does the method have parameters? (just a rhetorical question meant to indicate a certain level of anger and frustration - you don't need to answer it).

John - why not use something like this[^]? It's simple and much more effective.
