First if all, this is the WPF forum (and not the Silverlight forum).
For a silverlight sample on an editor, see here.

Hi together,
I use the DataGrid-Control to display the content of the ObservableCollection<Node> CriteriaNodes, where the class "Node" contains some properties such as Title, Description, Value, etc.
When I run the project, the ObservableCollection is filled with 13 Node-Objects and, afterward, the Binding is set with
MyNodeGrid.ItemsSource = CriteriaNodes;
The loaded DataGrid now shows only the column-headers of the Node-Objects. When I create new Nodes at runtime, they are added BELOW 13 lines of free space in the DataGrid! When I order alphabetically, I can see some of my initialized 13 Nodes in those new lines.
I don't understand this strange behavior and would be grateful for help. Below is the constructor of the Code-Behind-class.
Daniel
public partial class RetrievingControl : UserControl
{
BusinessMain MyBusinessMain;
public ObservableCollection<Node> CriteriaNodes { get; set; }
public ObservableCollection<Node> AlternativeNodes { get; set; }
public ObservableCollection<Node> StakeholderNodes { get; set; }
public RetrievingControl(BusinessMain pBusinessMain)
{
MyBusinessMain = pBusinessMain;
CriteriaNodes = MyBusinessMain.CurrentProject.CriteriaNodes;
AlternativeNodes = MyBusinessMain.CurrentProject.AlternativeNodes;
StakeholderNodes = MyBusinessMain.CurrentProject.StakeholderNodes;
InitializeComponent();
MyNodeGrid.ItemsSource = CriteriaNodes;
}
.. and the XAML-Part:
...
xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data"
...
<data:DataGrid x:Name="MyNodeGrid" AutoGenerateColumns="True" </data:DataGrid>
...

I have the following in a WPF window trying to open an RDLC report using a WindowsFormsHost. When the report opens there is a report header with no data. The query has no parameters and I have previewed the data in the data set many times.
I have seen many attempts to explain the meanings of ReportDataSource.Name and ReportDataSource.value but it is not yet clear to me what each is supposed to mean. I have not been able to implement anything but that which is listed below.
Thanks -
string reportPath = "C:\\Dev\\2010\\2010_BoxingAdmin\\BoxingAdmin\\BoxingAdmin\\Report1.rdlc";
string ds = "DEVELOPMENT;Initial Catalog=Boxing;Integrated Security=True";
ReportDataSource rds = new ReportDataSource("DataSet1", ds);
ReportViewer reportViewer = new ReportViewer();
reportViewer.ProcessingMode = ProcessingMode.Local;
reportViewer.LocalReport.ReportPath = reportPath;
reportViewer.LocalReport.DataSources.Add(rds);
windowsFormsHost1.Child = reportViewer;
reportViewer.RefreshReport(); Reply

When I use XamlWriter with my usercontrol I obtain usercontrol XAML and the xaml tree of my usercontrol
<my:myusercontrol canvas.left="100" canvas.top="100">
<grid>
<textbox text="Ciao Mondo">
<grid>
instead
<my:myusercontrol canvas.left="100" canvas.top="100">
MyUserControl inherits from Usercontrol or ContentControl and is compiled in a external DLL.
Why WPF windows control Button, TextBox, etc... when is Serialized from XamlWriter hide their content?

I would like develope a WPF application to create Silverlight application, in this application I realize XAML files that guest
my silverlight library.
I have thought to use an equivalent WPF library that is a replica of
silverlight library and I could use these controls in my application, and then with xaml code compile and create xap files.
Expression Blend and Visual Studio 2010 are WPF and desktop application
but they can edit silverlight windows. How do they work?
Thanks,
Fabrizio

I need display an image while selcting an item from combobox....like
combobox1_selecttionchanged
{
image1.visibilty==true;///this one giving error
}
wht i hv to do to display an image
With Regards
Ch.Gayatri

If you are trying to change visibility of image control then,
image1.Visibility = Visibility.Visible;
But you can directly bind the image source from the XAML itself. You may need an IValueConvcerter for converting selected item to image source.

You need a ContentPresenter in your ControlTemplate and set the TargetType of the ControlTemplate too.
<Window.Template>
<ControlTemplate TargetType="{x:Type Window}">
<Grid>
<Rectangle Stroke="Black" RadiusX="97.5" RadiusY="97.5" >
<Rectangle.Fill>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="Black" Offset="0"/>
<GradientStop Color="White" Offset="1"/>
</LinearGradientBrush>
</Rectangle.Fill>
</Rectangle>
<ContentPresenter />
</Grid>
</ControlTemplate>
</Window.Template>

I have a list
List<submissionworkflow> listSWF
that i bind to a datagrid and that works fine like this:
toolkit:DataGridTextColumn Binding="{Binding Title}" Header="Emne"
But the 'SubmissionWorkflow' object have a property 'Participants' that is a collection of objects of the type 'Participant' and when I try to bind like this
toolkit:DataGridTextColumn Binding="{Binding Path = /Participants[0].Name}" Header="Participants name"
Nothing happens.
What am I doing wrong?

Remove the slash from before Participants[0]. As a hint, always check the Output window when running your app if you are getting binding errors.
