Hi everybody.
How can I modify a XML file into Isolated Storage with silverlight 2 ? (without using LINQ)
For example : assume we have a XML file like this :
<CodeColorizer>
<Settings>
<IsVB>False</IsVB>
<IsStriped>False</IsStriped>
</Settings>
</CodeColorizer>
Now , I wanna change the content of IsVB to True .
How can I do it ?
By the way : I've already searched in Google, unfortunately I couldn't find anything special 
Thank in advance.

I've checked it out. We couldn't modify a XML file with the link.

Because using LINQ in SL2 causes we force to add some DLLs to our projects.
It means we will have a SL2 Application with a larger volume.

Mmm...
Haven't used XMLWriter on SL, but in theory you can generate a file using XML Writer on SL, mmm... I guess what you want is just modify the file without rewriting it isn't it?
More about XMLWriter and SL

If you just want to modify a single setting, you try to open it as a text file and then just check with a regex where the nodes are (a bit crappy stuff but should work).
Another curiosity, how much extra weight did ad the LINQ to your XAP?

Yeah, I think ,I have to do it.

If we using LINQ , we have to add some DLLs beside the SL2 project.

In my case (dbschemaeditor.com) I'm using LINQ To XML, and I have developed a desktop like app and the release mode of the XAP is just about 3OO kbytes (in your case the DLL's that you will be added will be compressed by the SL and added to the XAP), I could shorten it by chopping it into several XAP, and load features on demand, and use caching on the isolated storage.
What's the size of your XAP? Have you checked on Release mode?
Cheers

About 1.2 MB

Ouch !
Mmmm... Or it's a hugue project, or there's something wrong going there.
My solution is composed of 12 projects and more than 100 classes, maybe not a big project but at least medium sized.
Have you checked what does take that hugue size? Are you embedding images or any expensive resource? Pure code shouldn't take that much.
If you want to analyze how longs takes each part of the XAP, you can rename the file top ZIP and then unpack it and check sizes of DLL's, resource, and folders.

I'm trying to set up a toggle button that changes the image when the button is checked/no checked. Consider the following XAML:
<style targettype="ToggleButton" x:key="PushPinButton" mode="hold" xmlns:x="#unknown" /> <Setter Property="Template" />
<Setter.Value>
<ControlTemplate TargetType="ToggleButton">
<Image Source="/CometWPF2;component/Icons/blue_pushpin.png" Margin="0"
VerticalAlignment="Center" HorizontalAlignment="Center" />
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter Property="Template" />
<Setter.Value>
<ControlTemplate TargetType="ToggleButton">
<Image Source="/CometWPF2;component/Icons/red_pushpin.png" Margin="0"
VerticalAlignment="Center" HorizontalAlignment="Center" />
</ControlTemplate>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
</Style>
The IDE is telling me that the Setter.Value attachable property doesn't exist. I have no idea if I'm doing this anywhere close to correctly...
I did this and it works:
<Image Source="/CometWPF2;component/Icons/blue_pushpin.png" x:Key="PinUp" />
<Image Source="/CometWPF2;component/Icons/red_pushpin.png" x:Key="PinDown" />
<Style TargetType="ToggleButton" x:Key="UDPPushPinButton">
<Setter Property="Content" Value="{DynamicResource PinUp}" />
<Style.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter Property="Content" Value="{DynamicResource PinDown}" />
</Trigger>
</Style.Triggers>
</Style>
Now I want to get rid of the border that shows up (and remains displayed) when it's clicked.

The Setter tag is closed. <Setter Property="Template" /> should be <Setter Property="Template" >. The Style tag too.
XAML is well-formed XML.

Add:
<Setter Property="FocusVisualStyle" Value="{x:Null}"/>
So it will be something like:
<Image Source="/CometWPF2;component/Icons/blue_pushpin.png" x:Key="PinUp" />
<Image Source="/CometWPF2;component/Icons/red_pushpin.png" x:Key="PinDown" />
<Style TargetType="ToggleButton" x:Key="UDPPushPinButton">
<Setter Property="Content" Value="{DynamicResource PinUp}" />
<Setter Property="FocusVisualStyle" Value="{x:Null}"/>
<Style.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter Property="Content" Value="{DynamicResource PinDown}" />
</Trigger>
</Style.Triggers>
</Style>

Good People,
So I have been developing my application fine now (for about 3 months) then out of the blue, Visual Studio will not show any of the user controls I have created and Expression Blend will crash when I try to show any data template.
Back in Visual Studio, it's telling me that it can't find a static resource referenced in my resource dictionary and then it notifies me that in App.xaml the Source property of resource dictionary cannot be set to my resource dictionary. I am puzzled. It builds fine and executes fine. The xaml files all have their appropriate namespaces and scope.
I checked online and someone, in 2008, said this was a bug. Of course, I tried to download visual studio 2008 service pack 1 but that installation always hangs, never downloads and doesn't install any files. I have .net 3.5 sp1.
Any thoughts or ideas would be deeply appreciated.
Thanks,
Blitz
So, the problem was that I had to move the resources to the top of the resource dictionary file so it could find them.
#$%%^$#@@#$$ you WPF!
Anyway, I'm happy again

By the way, these resources are defined in the Resource Dictionary using the right key - e.g. "StringToBoolConverter", but it is still unable to find them.
In addition, I wonder why these problems would start now and not earlier.

Hello.
Is it possible to place a Canvas or Grid inside a Viewport3D, to enable a flip or skew animation? Simply adding a canvas as a child doesn't work, so I'm wondering if there is another way?
Regards, E.

You're right, I don't think that you can just stick UIElements into ViewPort3D.
One option is to try to simulate your desired 3D animation with the regular 2D system. For example, check out this blog post by Tess Ferrandez which shows how to do a flip between 2 UI elements:
Silverlight/WPF FlipImage Animation[^]
If you are using these animations as transitions and don't need to have active UI elements during those transitions, you may be able to persist your UI elements to an image and have that applied to a 3D element which you can add to your ViewPort3D.

Hi.
I'm reading a XML file that has been stored in IsolatedStorage.
But this Exception was occurring Root element is missing.
I'm dead sure that there isn't any troubles in the XML file, So I don't the know the result of the Exception
Could you guide me ?
Thank you.
This is my snippet code :
using (IsolatedStorageFile isoStore = IsolatedStorageFile.GetUserStoreForApplication())
{
.
.
.
string SettingFilePath = "CodeColorizer\\setting.xml";
using (IsolatedStorageFileStream isoStream = new IsolatedStorageFileStream(SettingFilePath, FileMode.Create, isoStore))
{
isoStream.Position = 0;
XmlReader xmlReader;
xmlReader = XmlReader.Create(isoStream);
<code>xmlReader.MoveToContent();</code>
string value;
while (xmlReader.Read())
{
switch (xmlReader.NodeType)
{
case XmlNodeType.Element:
{
if (xmlReader.Name == "IsVB")
{
value = (string)xmlReader.ReadContentAs(Type.GetType("String"), null);
if (value == "True") { this.IsVB.IsChecked = true; this.IsCsharp.IsChecked = false; }
else if (value == "False") { this.IsVB.IsChecked = false; this.IsCsharp.IsChecked = true; }
}

Is FileMode.Create really the mode you want to open the file in?

Thanks Mark.
I've altered it to FileMode.Open , but the Exception has occurred again

I have the following code
<Border Margin="3,4,0,0" Height="205" VerticalAlignment="Top" BorderBrush="Black"
BorderThickness="2" HorizontalAlignment="Left" Width="891" CornerRadius="8,8,8,8">
<StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" >
<StackPanel.Clip>
<RectangleGeometry Rect="0,0,891,205" RadiusX="8" RadiusY="8"></RectangleGeometry>
</StackPanel.Clip>
<Label Height="26" Name="label1" Width="205" HorizontalAlignment="Left" VerticalAlignment="Top"
HorizontalContentAlignment="Center" VerticalContentAlignment="Center" FontFamily="Arial" FontSize="14"
FontStyle="Italic" FontWeight="Bold" Content="Contacts" Background="Black" Foreground="LightSteelBlue"
ClipToBounds="True">
<Label.LayoutTransform>
<RotateTransform Angle="270" />
</Label.LayoutTransform>
</Label>
<telerik:RadGridView Name="gridviewContacts" AllowDrop="False" Height="203" VerticalAlignment="Top"
Margin="0,0,0,0" AutoGenerateColumns="False" FontFamily="Arial" ClipToBounds="False"
Width="863">
<telerik:Theming.Theme>
<telerik:VistaTheme />
</telerik:Theming.Theme>
</telerik:RadGridView>
</StackPanel>
</Border>
Essentially, I have a Border that contains a horizontally oriented StackPanel that contains a Label and a Telerik RadGridView. I want to put rounded corners on the Border element, and clip all of the other elements within the Border to not render outside the rounded corners.
The code above contains my latest non-working attempt. I tried to use the ClipToBounds property, but that doesn't seem to do anything.
