I don't know anything about silverlight but I am using firefox 3 and the silverlight page was really slow compared to the flash page.
I didn't get any requirements for the signature

I have a combobox where the ItemsSource is bound to a ObservableCollection<string> and the SelectedItem is bound to a string DependencyProperty.
The ObservableCollection<string> is populated so that the first string is an string.empty, so that something by default is not selected.
My problem is this, if I select something in the combobox beside the string.empty (by clicking the drop down arrow and left clicking on an item, you can click the drop down arrow and select the string.empty item. However you can use the scroll on the mouse and select the string.empty. Then the caveat is that you can not scroll with the mouse to something that is not string.empty, you have to hit the drop down arrow and select an item with a left mouse click.
Any ideas, this has me stumped.

What does this binding look like?
I can't reproduce the problem if this binding is left out.

I took your scenario and binded by creating the dependency property, for me everything works. Once the mouse is over the combo box and combobox has the focus , scrolling works fine with the mouse. you can only post a sample so that actual issue can be observed
<ComboBox x:Name="cboDistrict" IsSynchronizedWithCurrentItem="True"
Grid.Column="1" Grid.Row="0" Style="{DynamicResource BaseComboBox}"
ItemsSource="{Binding Path=AllDistricts, Mode=Default}"
SelectedItem="{Binding Path=BodyTextDistrict, Mode=TwoWay}">
<ComboBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding }"/>
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
Private Property AllDistricts() As ObservableCollection(Of String)
Get
Return DirectCast(GetValue(AllDistrictsProperty), ObservableCollection(Of String))
End Get
Set(ByVal value As ObservableCollection(Of String))
SetValue(AllDistrictsProperty, value)
End Set
End Property
Public Shared AllDistrictsProperty As DependencyProperty = _
DependencyProperty.Register("AllDistricts", GetType(ObservableCollection(Of String)), _
GetType(NameView), New UIPropertyMetadata(New ObservableCollection(Of String)))
Public Property BodyTextDistrict() As String
Get
Return Convert.ToString(GetValue(BodyTextDistrictProperty))
End Get
Set(ByVal value As String)
SetValue(BodyTextDistrictProperty, value)
End Set
End Property
Public Shared BodyTextDistrictProperty As DependencyProperty = _
DependencyProperty.Register("BodyTextDistrict", GetType(String), _
GetType(NameView), New UIPropertyMetadata(String.Empty))

I don't know what it means. It's XAMLParseException:
Cannot convert the value in attribute 'Style' to object of type 'System.Windows.Style'. Specified element is already the logical child of another element. Disconnect it first. Error at object 'buttonPushPin' in markup file 'CometWPF2;component/controlcrm.xaml' Line 42 Position 23.
Here's the offending code:
<ToggleButton Style="{DynamicResource UDPPushPinButton}" Name="buttonPushPin"
Width="26" Height="23" Margin="0,0,19,0" HorizontalAlignment="Right" VerticalAlignment="Top"
BorderThickness="0" Background="Transparent" BorderBrush="Transparent"
ToolTip="Pin this tab" />
More Info: This button is in all of the tabs in a tab control, and this error occurs when more than one tab (with the button) is added to the tab control. The tabs all contain a UserControl that has the button it.

Set x:Shared="false" for this. This creates a unique instance instead of a static instance.

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

Do you want to send it to me and I'll have a look? You've got my email address.

Let me see if I can cut it down to a minimal project.

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....

That will be in the control template. Here's the default template ripped from
a control on Vista:

<Rectangle Stroke="Black" StrokeDashArray="1 2" StrokeThickness="1" Margin="2" SnapsToDevicePixels="true"/>

<GradientStop Color="#CDCDCD" Offset="1"/>
</LinearGradientBrush>
<SolidColorBrush x:Key="ButtonNormalBorder" Color="#FF707070"/>
<Style x:Key="ToggleButtonStyle1" TargetType="{x:Type ToggleButton}">
<Setter Property="FocusVisualStyle" Value="{StaticResource ButtonFocusVisual}"/>

<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
<Setter Property="HorizontalContentAlignment" Value="Center"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="Padding" Value="1"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ToggleButton}">

ASP.NET I would guess. I see no WebMonthView control in Silverlight

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.
Braulio Dez wrote: 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

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
