You need to HTML encode your code when you paste it. I can't read this.

hehe, sorry, forgot =)
i fixed it in the previous post

It's still not quite right. Your observable collection appears to not have a templated type. And I'm not sure that I saw "System.Collections.ObjectModel" included (for ObservableCollection).

I was able to confirm your problem and I did some searching. I came across this. Basically, I think DataGrid handles scoping incorrectly, so when you say "ElementName=", the binding is not able to find anything outside of the DataGrid. To get around that, you use a relative source instead of element name:
<Button Content="Show Popup" Command="{Binding Path=DataContext.ShowMyPopUp, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}" />

Hi All,
I'm just implementing my first Silverlight WCF service in an ASP.NET web site hosting a Silverlight client and have run into a problem.
The service and client are working together fine, I've just done a little "Hello World" test on the two communicating. Now I'm ready to move onto the implementation and the guts of the service.
In a normal WCF setup for me I would create a separate class library project containing the service contract and any required domain objects. Then I can link to that from the service and the client and get all the same objects used at both ends of the pipe.
However, I'm running into an error:
Could not load file or assembly 'System.ServiceModel, Version=2.0.5.0
I'm assuming this is because the service and client are using two different versions of .NET. So the Core library is getting compiled in one environment and then told to run in two, fail! 
Is there a work around for this?
Cheers,
|

Either use .NET 4 which allows this (in a somewhat limited way), or you need to create a separate Silverlight DLL and link your classes in as external items."WPF has many lovers. It's a veritable porn star!" - Josh Smith As Braveheart once said, "You can take our freedom but you'll never take our Hobnobs!" - Martin Hughes.

Hi Pete,
I tried this both ways, making a normal class library and a silverlight class library and each time either the client or the service complained about the runtime version.

Sorry. I dont think I can understand you question completely.
For popups, see here[^]. Searching on the internet should give you plenty more popup options.
If you want to pass something between Javascript and Silverlight - use the html bridge as described here[^].Me, I'm dishonest. And a dishonest man you can always trust to be dishonest.

Hi,
I wanted to create wpf controls dynamically based on a business model.
for that i tried to use DataTemplates for creation of controls based on values from an array. And then bind the array to ItemControls Itemsource.
I used this example for testing.. This is what i did..
< Window x:Class="Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="dialog" xmlns:sys="clr-namespace:System;assembly=mscorlib"
Width="393.412" Height="333.4">
< Window.Resources>
< ResourceDictionary
Source="ResourceDictionary\ControlCreatorDataTemplate.xaml"/>
</ Window.Resources>
< StackPanel>
< ItemsControl ItemsSource="{Binding Source={StaticResource data}}" Visibility="Visible" />
</ StackPanel>
</ Window>
resource dictionary
< ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:sys="clr-namespace:System;assembly=mscorlib">
< x:ArrayExtension Type="{x:Type sys:Object}" x:Key="data">
< sys:String>String</ sys:String>
< sys:Boolean>True</ sys:Boolean>
< sys:Boolean>False</ sys:Boolean>
< sys:Double>10.0</ sys:Double>
</ x:ArrayExtension >
< DataTemplate DataType="{x:Type sys:Boolean}" >
< CheckBox Content="CheckBox" IsChecked="{Binding Mode=OneWay}" />
</ DataTemplate >
< DataTemplate DataType="{x:Type sys:String}" >
< TextBox Text="{Binding Mode=OneWay}" />
</DataTemplate >
< DataTemplate DataType="{x:Type sys:Double}" >
< TextBox Text="{Binding Mode=OneWay}" />
</ DataTemplate >
</ ResourceDictionary >
Problem is i am able to view the checkbox and text in the designer window in VS08
When i run the window -> the controls are not visible...
Any help is appreciated

Hi,
I have a class which derives from TextBox called EntryTextBox and provides a PreviewKeyDown event handler (although for the purposes of this question, it's not relevant).
I have produced a ControlTemplate within a style as follows:
<Style TargetType="{x:Type my:EntryTextBox}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type my:EntryTextBox}">
<DockPanel>
<Border BorderThickness="1" HorizontalAlignment="Stretch" BorderBrush="DarkGray" Background="White" Width="100">
<DockPanel>
<Button DockPanel.Dock="Right" Visibility="{Binding Path=KeyboardPopup,Converter={StaticResource VisibilityConverter},RelativeSource={RelativeSource TemplatedParent}}">
<ContentControl Width="15" Height="10" Template="{StaticResource KeyboardIconContent}"/>
</Button>
<ScrollViewer Margin="0" Background="Transparent" HorizontalAlignment="Stretch" x:Name="PART_ContentHost"/>
</DockPanel>
</Border>
</DockPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Which as you can see displays a Button as part of the TextEntry box depending on the value of KeyboardPopup. This works fine, but I want to be able to act on the button's click handler from within my EntryTextBox class but don't know how to do it.
I've read in "Pro WPF in C# 2008, Matthew MacDonald, P872" that you need to "give your elements recognisable names and attach event handlers to them programatically in the control constructor" but I am unsure of the syntax I should use in the class constructor of EntryTextBox.
Can anyone help me?
Cheers
Richard

1. Name the button something line "PART_Button".
2. Then override OnApplyTemplate().
3. In OnApplyTemplate use GetTemplateChild("PART_Button").
That will get you a reference to the button to add your event handler. Of course you will want to check the returned object to make sure is is not null. Someone may change the template for your control.

Thank-you rhuiden, you are a star! That's exactly what I was after.

I think one type is programming is no more, or less, difficult than another. It's all about understanding the tools, techniques, environment, etc.

I think, as originally stated, you should move this to the lounge. It would be a better place to have such a discussion since, once again, the forums are for questions and don't seem to have any, only opinions and a need to discuss your difficulty in keeping up with the body of knowledge in this career field.

Bute now i change all the basic control properties(like Color, MArgins,Size, etc..) from the MyPage.xaml to App.xaml where i defined the Styles declaration.

Thanks
