Hi there,
I'm new to WPF, so bear with me..
I have a Main View, and a view within it. I set the DataContext in my 'OnStartup' C# method:
Views.MainView view = new Views.MainView();
view.AssignmentView.DataContext = new ViewModels.MainViewModel(_assignmentDataSource);
I have previous / next button in my 'AssignmentView', that are linked to commands. This Moves focus from record to record as expected in my ListView, in my XAML :
<ListView Margin="10" ItemsSource="{Binding Assignments}" Grid.Row="0" BorderThickness="1" Background="{x:Null}" Foreground="Black">
<ListView.View>
<GridView>
<GridViewColumn Header="Assignment Name" DisplayMemberBinding="{Binding AssignmentName}>
</GridView>
</ListView.View>
</ListView>
Great.
However, when I use the following Stack Panel, the TextBox data does not change when I press previous / next. It stays on the first record.
<StackPanel Grid.Row="1" Orientation="Vertical" DataContext="{Binding Assignments, Mode=TwoWay}"/>
<StackPanel Orientation="Horizontal"/>
<Label Content="Assignment Name:" Margin="0,0,4,0"/>
<TextBox Width="158" Text="{Binding Path=AssignmentName}"/>
</StackPanel>
</StackPanel>
I think its a problem with the 'DataContext' - I don't think I should be wiring it up in the Stack Panel, but when I remove it, there is no data in the Stack Panel text box..
Where am I going wrong?
Any help greatly appreciated. Thanks.
Jon

You will need to write animcation transformation code on keydown to move these controls.
See here[^] for an example.Me, I'm dishonest. And a dishonest man you can always trust to be dishonest.

You would need to move the the textblock relative to the canvas and grid, not relative to the page.
I hope that helps.Me, I'm dishonest. And a dishonest man you can always trust to be dishonest.

yes m doing the same as u said but when i move texrblock, it can move outside the Canvas or Grid but i dnt want to move Text Block outside the Canvas or Grid...
any solution??

You will need to write your some code to check if the textblock is moving outside the canvas. If it is, you do not allow it to move (transform) further.Me, I'm dishonest. And a dishonest man you can always trust to be dishonest.

I could not locate a sample, but this is what I would do in the LayoutUpdated handler -
if ((((FrameworkElement)myControl).DesiredSize.Width) > myContainer.Width)<br />
{<br />
_translateTransform.X = myContainer.ActualWidth -(((FrameworkElement)myControl).DesiredSize.Width);<br />
}
The same thing needs to be implemented for the y co-ordinate.
Hope it helps.Me, I'm dishonest. And a dishonest man you can always trust to be dishonest.

Every control has a Canvas.ZIndex property.
Check if this[^] z-index value is able to give you the layer effect.Me, I'm dishonest. And a dishonest man you can always trust to be dishonest.

Hello, I have created a new article
Automatic WPF mapping to Database (Access 07 edition)[^]
and I would improve some parts if it's possible, I created a list of controls,dependency properties,string like:
mapping.CustomAdd(C1_Name,TextBox.TextProperty,"Name");
where the third column is the name of a field and by reflection I get/set the value of the class. My question is:
Is too much overheard add dependency properties linked to fields of a custom class? The class has to inherit from control?
Any example of implementing it would be great, Thanks

I've added my comments against your article, but I'll reiterate here for anybody who doesn't go over. I'm surprised that this implementation doesn't use MVVM. It would be worth looking to put that into place to make things easier for yourself."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.

Hello I'm trying to format a DateTime in XMAL, I found one page that explains that but in my case is not usefull. I want to put a format to DateTime value when it is binding, I have this piece of code:
ToolTip Name="Tooltip1" Style="{StaticResource TooltipStyle}" Content="{Binding
Converter={StaticResource dataPointConverter},
ConverterParameter='Date:{#XValues:}{#NewLine}Measure: {#Value}'}" >
<ToolTip.RenderTransform>
<TransformGroup>
<ScaleTransform x:Name="ScaleTransofrm2"
CenterX="30" CenterY="20"/>
<RotateTransform x:Name="RotateTransform1"
CenterX="30" CenterY="0"/>
</TransformGroup>
The XValue is the value that I want to format (this is the datetime).
If someone knows how to do that, I will be appreciated.
Regards and thanks in advance.

You could put in some logic in your converter to format date values based on the converterparameter. Not a pretty way to do it, but it might work.Me, I'm dishonest. And a dishonest man you can always trust to be dishonest.

I am getting the following exception when trying to save a canvas in a wpf xaml file.
An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll
The following is what I did:
I am having a canvas in a wpf window which contains a chart and some labels.
<Canvas x:Name="c1">
<chartingToolkit:Chart x:Name="Time_Distance_Graph" Width="1292" Height="800" Canvas.Left="2" Canvas.Top="50" BorderThickness="0" xmlns:chartingToolkit="clr-namespace:System.Windows.Controls.DataVisualization.Charting;assembly=System.Windows.Controls.DataVisualization.Toolkit">
<chartingToolkit:Chart.Resources>
<Style x:Key="LineDataPointStyle" TargetType="charting:LineDataPoint" xmlns:charting="clr-namespace:System.Windows.Controls.DataVisualization.Charting;assembly=System.Windows.Controls.DataVisualization.Toolkit">
<Setter Property="Visibility" Value="Hidden"/>
</Style>
</chartingToolkit:Chart.Resources>
<chartingToolkit:Chart.Axes>
<chartingToolkit:LinearAxis Orientation="X" Maximum="48" Interval="1" Title="Time" Margin="0,20,0,0" Visibility="Hidden" Minimum="0" ShowGridLines="False" />
<chartingToolkit:LinearAxis Orientation="Y" Title="Distance" Maximum="35" Minimum="0" Interval="0.5" Visibility="Hidden" ShowGridLines="False" />
</chartingToolkit:Chart.Axes>
<chartingToolkit:Chart.LegendStyle>
<Style TargetType="Control">
<Setter Property="Width" Value="0"/>
<Setter Property="Height" Value="0"/>
</Style>
</chartingToolkit:Chart.LegendStyle>
<chartingToolkit:Chart.ChartAreaStyle>
<Style TargetType="Panel">
<Setter Property="Width" Value="1259"/>
<Setter Property="Height" Value="743"/>
</Style>
</chartingToolkit:Chart.ChartAreaStyle>
</chartingToolkit:Chart>
<Label Canvas.Left="1095" Canvas.Top="37.5" Height="25" Width="37.5" Content="Date:" Name="lblDate"/>
<Label ………………………/>
<Label ………………………/>
<Label ………………………/>
</Canvas>
And also from the code behind I am adding more labels and lines dynamically to the canvas according to the requirement.
When the save button is clicked.
The following code is set to be executed.
FileStream saveFile = new FileStream(filepath, FileMode.Create);
XamlWriter.Save(c1, saveFile);
How can I get rid of the above exception?
Expecting a soon reply.
Thanks in Advance.

I have a accordion control on which I have databound two properties from the database. One is Location and other is theatre. When the page loads, the accordion shows different locations for each of the theatres. Actually I want only a single location for the theatres which come under that theatre part.
The screen shot for reference is as follows
http://lh4.ggpht.com/_rZz85WGZ4Vg/S5UhufYlUZI/AAAAAAAAAWQ/zXZiG4HTV9o/myScree.JPG[^]
The XAML code for the accordion is as follows:
<br />
<layoutToolkit:Accordion HorizontalAlignment="Stretch" Grid.Row="1" VerticalAlignment="Stretch" Grid.RowSpan="2" Margin="0,0,0,40" BorderBrush="{x:Null}" x:Name="theatresAccordian"><br /><br />
<layoutToolkit:Accordion.ContentTemplate><<br />
<DataTemplate><br />
<TextBlock Text="{Binding Name}"/><br />
</DataTemplate><br />
</layoutToolkit:Accordion.ContentTemplate><br />
<layoutToolkit:Accordion.ItemTemplate ><br />
<DataTemplate><br />
<TextBlock x:Name="_headertext" Text="{Binding Location}"/><br />
</DataTemplate><br />
</layoutToolkit:Accordion.ItemTemplate><br />
</layoutToolkit:Accordion><br />
I have tried searching search engines but was in vain  Always Keep Smiling.

I have a WinForms app with an embedded WPF user control. The embedded WPF UserControl contains a ListView.
The application implements a List collection that MUST remain compatible with the already existing Winforms code (for various reasons that aren't important here, the list cannot inherit from IBindingList or ObservableCollection). For this reason, the WPF ListView isn't updated when the contents of the list changes, which means (I think) that I'm relegated to adding/changing the items manually when they've changed.
Everything I've found on the web assumes that I'm using purely WPF (and an ObservableCollection), and thus assumes I'm using databinding (which I'm not, obviously).
I know how to add items to the ListView manually, but how do I tell the ListView columns what property to use from the added item?.45 ACP - because shooting twice is just silly
