Hi,
I am using .net 4 visual studio 2010 premium.
I have been given a silverlight project to work on which was created in silverlight 3.
I can run the application but can not debug it.
The properties of the application shows that the target silverlight version is set to silverlight 3 and this is the only option available.
Note that I have installed silverlight 4.
And in the web.config of the host, the following line is indeed present
<compilation debug="true">
Question:
How can I debug the application based on the above please?
Thanks

So when you place a break point on the Code behind it does not go ?

I want to use an expander control to contain a shadowbox style filter user control. So the basic idea is to make the expander button look like a filter button, and upon pressing a grid with some controls in it will appear in the center of the current window while the rest of the window is overlaid with a semi-transparent grid.
All the code for this is easy enough, but I am having trouble with expanded width of the expander vs. collapsed width. I want something along these lines:
<Style
x:Key="sbExpander"
TargetType="{x:Type Expander}">
<Style.Triggers>
<Trigger
Property="IsExpanded"
Value="True">
<Setter
Property="Background"
Value="Black" />
<Setter
Property="Opacity"
Value=".8" />
<Setter
Property="Width"
Value="760" />
<Setter
Property="Height"
Value="760" />
</Trigger>
</Style.Triggers>
</Style>
The expander control:
<Expander
Grid.Row="0"
Grid.Column="0"
Grid.RowSpan="10"
Grid.ColumnSpan="4"
IsExpanded="False"
HorizontalAlignment="Left"
Width="20"
ExpandDirection="Right"
Style="{StaticResource sbExpander}">
<Grid
Width="760"
Background="Black"
Opacity=".8">
</Grid>
</Expander>
The issue is that if the initial width of the expander is anything greater than 20 it overlays the rest of my controls and renders them unusable. I only want them unusable when the expander is expanded. So I really do want the collapsed expander control width to be 20 so that the controls under are available, while I want the expanded width to be 760 covering the entire window.
Thoughts?
Cheers, --EA

Ok, I figured it out. Put the expander inside a stackpanel whose width property was set to auto.

Hi,
I am running visual studio 2010 premium with silverlight toolkit 4.
The project does not build and in references, the following dlls have yellow exclamation next to them:
1- Microsoft.Expression.Interactions
2- System.Windows.Interactivity
How can I solve these please?
Thanks

This [^] might help.
The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

Hi!
I am making a full screen WPF application. Please tell me what is right way to make full screen application in one window. How to change screens/views? All views as custom controls? Or just hide elements or create them dynamically? I couldn't find the answer.
Thanks.

You might actually want to look at an application block like Microsoft Prism[^].
By using this, you can divide your screen into regions and then add and remove views (xamls) from these regions based on your business requirements.

Hi
The RichTextBox has no Text property which to bind to show data from database..so are there workarounds to do this???
Thanks

It seems a hard work to bind the richtextbox...

Seems dam near impossible to bind a RTB, thankfully my requirement could be met but a simple textblock and I moved on, but I spent a couple of weeks ratting around trying to find an decent solution to this and failed.

hi Mycroft Holmes,
so did you use a TextBlock instead of a RTB???
But a simple texbolock can't show images, grids, calendar etc...am i right??
bye
thanks

Absolutely you are correct, my requirements were actually extremely simple, some fancy formatting which I convinced the client to reduce to bullet points which are supported by the textblock.
Your requirement completely contradicts your initial issue, what has a text property have to do with a grid, calendar or image.

 yes..but the main step was to bind the RTB, thereafter try to inserit some custom controls.

I was watching the video about upcoming Silverlight 5.0. I have an app I would like to port to the web and Silverlight appears to be the perfect platform. Is this all real hype or is it as good as Microsoft describes it.

It basically depends on your requirements.
You might want to compare and contrast some other technologies (like ASP.Net, HTML5) etc. before selecting SL.

Thanks in advance.
Without boring you to death with all the details - I have an EF model intended to track project requests. The hierarchy is that corporate divisions have departments; the departments submit project requests. The requests have to be categorized by risk and can fall into one or more categories. This last component is represented in the database via a Many-to-Many table incorporating the RequestIDs and the RiskIDs. EF eliminates the many-to-many table and shows the association between the Request and RiskCategory entities.
I've created a WPF form that ALMOST works they way I want, showing the users the details of their requests. I'd like to add to the form a combobox within a listview, from which the users can select the categories that apply to a given request. Only the combobox will be in the ListView
So..the CollectionViewSource for the RiskCategories table is categoriesViewSource, and the CollectionViewSource for the RequestItems is named
RequestItemsRiskCategoriesViewSource
The Datacontext of the ListView itself is set to RequestItemsRiskCategoriesViewSource, and the combobox's ItemsSource is set to the categoriesViewSource. Try as I might, I can only get the combox to display the available RiskCategories, not the ones already assigned to the current RequestItem. If there is one category assigned, then one combobox hows in the listview. If 3, then 3 comboxes appear. But each one displays the first category in the list, not the assigned categories.
Changing the datatemplate to a Textbox bound to Category works just fine, but gives the user no way to choose a valid value
<ListView.View>
<GridView>
<GridViewColumn x:Name="categoryColumn" Header="Category" Width="80">
<GridViewColumn.CellTemplate>
<DataTemplate>
<ComboBox
ItemsSource="{Binding Source={StaticResource categoriesViewSource}}"
SelectedValue="{Binding Path=RiskCategory}"
DisplayMemberPath="Category">
</ComboBox>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
</GridView>
</ListView.View>
[edit] - I posted XAML from a listview, not a datagridview. I can get the listview to work, but not a datagridview
Any ideas what I'm doing wrong? Do I have to handle M-M relationships differently?
Thanks again

Are you using a viewmodel to supply data to the view? If the datacontext of the view is the viewmodel, you might have to use a relative source to access the proper data context.
ex:
<ComboBox
ItemsSource="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}},Path=DataContext.DocRefTypes}"
DisplayMemberPath="Type"
SelectedValuePath="Id"
Grid.Row="2"
Grid.Column="1"
Margin="5,1,4,1"
Width="395"
SelectedValue="{Binding ReferenceType}"
HorizontalAlignment="Left"/>
It really depends on the data context for the container of your control, but if the parent container or control has a datacontext set on a viewmodel, this might work for you. Change the Path to point to whatever the ObserveableCollection(?) that you are trying to bind to.

Thanks for the response. I'm a part time 'programmer' trying to learn C# and WPF after years (and years) of Excel VBA and some T-SQL. The MVVM learning process has been VERY slow for me as I completely lack experience in creating and, more importantly, programming with POCO classes. All my past work that required data access used direct connections to the db and calls to stored procedures.
So, in a long winded fashion I'm replying that this WPF attempt is not using MVVM concepts and I'm trying to databind to EF EntitySets and EF entities.
Because of the issue in the original question and some other problems, I've paused the project while trying to get some MVVM education. Still am struggling to find any non-trivial examples/explanations of how one goes from EF or LinqToSQL to MVVM models. While there is a tremendous amount of quality MVVM information available, here and elsewhere, there seems to be an ongoing assumption that the readers are well versed in getting from a database datastore all the way through the construction of the models. I see very little discussion about what concepts are important to incorporate, what the approach should be, etc.
Again, thanks for your response. Maybe I'll be back after making progress on the MVVM front.
