No workee. I also tried putting that on the style itself.

I have a very slimmed down app that duplicates the behavior. I'll have to wait until I get home tonight to send it to you.

Well, I got it not to crash by doing this:

<ImageBrush x:Key="PinUpBrush" ImageSource="/WpfTest;component/Icons/blue_pushpin.png" />
<ImageBrush x:Key="PinDownBrush" ImageSource="/WpfTest;component/Icons/red_pushpin.png" />
<Style TargetType="ToggleButton" x:Key="UDPPushPinButton2" >
    <Setter Property="Button.Background" Value="{StaticResource PinUpBrush}" />
    <Style.Triggers>
        <Trigger Property="IsChecked" Value="True">
            <Setter Property="Button.Background" Value="{StaticResource PinDownBrush}" />
        </Trigger>
    </Style.Triggers>
</Style>

Now all I gotta do is figure out how to make the border not show up when I click it....

Modify a XML file in Silverlight 2 ?

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 Frown | :(

Thank in advance.

Can you use XMLWriter on Silverlight, I guess yes, check this link

http://msdn.microsoft.com/en-us/library/cc189001(VS.95).aspx[^]

Just a curiosity, why you don't want to use LINQ To XML? works pretty well and it's pretty easy to use.

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

https://silverlight.net/forums/t/6655.aspx[^]

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?

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.

ToggleButton with Images [SOLVED - sort of]

#realJSOP14-Apr-09 9:58

#realJSOP

14-Apr-09 9:58

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:

XML

<Setter Property="FocusVisualStyle" Value="{x:Null}"/>

So it will be something like:

XML

<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>

Visual Studio 2008/Expression Blend Wierdness [SOLVED!!!]

BlitzPackage14-Apr-09 7:23

14-Apr-09 7:23

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 Smile | :)

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.

Canvas or Grid inside Viewport3D?

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?
