This class is not just for use by the ObservableCollection. BTW - ClearItems removes all items from the list, and raises the CollectionChanged for this. If you want bulk capability[^], I wrote an article a while back which provides this."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.

I suggest you reinstall the visual studio. Most of these problems will be solved in this way.

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.

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.

| There are some excellent articles here[^] on CodeProject for beginners in WPF; especially by Josh Smith & Sacha Barber. The book suggested by the previous poster is also worth investing in. txtspeak is the realm of 9 year old children, not developers. Christian Graus

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
