Thanks. I'm going to try to implement your code in some fashion. I had tried the INotifyPropertyChanged, but couldn't get it to work, because I couldn't figure out where the new value was and how to store that new value in my zonedescrip[zonenum] array.
My code should be a little simpler. The Zone number never changes (a zone is a zone). The description is the only thing that can change. And, when it does, it goes back into a zonedescrip[zonenum] array. When the user clicks on a SAVE button, the zonedescrip array gets saved into a permanent place.
I need to figure out how your Edit calls work. Maybe I don't even need a temporary zonedecrip array. Just use the permanent array as the Source and copy back to the permanent array when the user clicks on SAVE. During what part of the user editing process do the BeginEdit, EndEdit, and CancelEdit methods get called?

You can always fetch the ListBox control using VisualTreeHelper and then set its items to Labels intead of TextBoxes.

I'd want to make users authenticate with username and password credentials before loading the shell (a common scenario), I want to show the login page, but after bootstrapper starts, because I want to use my Authentication Service, thats registered with container, and if user authenticates then to show the shell.

It's a bit of a pain to do - look at flexgrid's CellFactory

The XAML's a bit long here, so please bear with me.
I have styled an expander to look like this[^].
I am very new to styling, so I could use some help. When the expander is collaped I want the rectangle and arrow to be gray. When expanded, I'd like to change the color to orange. I would also like to redraw the arrows facing up.
I got the idea from the expanders here[^].
I really don't know how to go about doing this. Could someone point me in the right direction?
The XAML is
<Window.Resources>
<Color x:Key="Color1">Gray</Color>
<Color x:Key="Color2">SlateGray</Color>
<Color x:Key="Color3">DarkSlateGray</Color>
<Color x:Key="HeaderGradientBrush1">DarkGray</Color>
<Color x:Key="HeaderGradientBrush2">White</Color>
<SolidColorBrush x:Key="ToggleButtonEllipseBorderBrush" Color="{StaticResource Color1}" />
<SolidColorBrush x:Key="ToggleButtonArrowBrush" Color="{StaticResource Color2}" />
<SolidColorBrush x:Key="ToggleButtonRectangleBrush" Color="{StaticResource Color2}" />
<SolidColorBrush x:Key="ToggleButtonBackgroundBrush" Color="Transparent" />
<SolidColorBrush x:Key="ContentAreaBackgroundBrush" Color="Transparent" />
<SolidColorBrush x:Key="ExpanderBorderBrush" Color="{StaticResource Color1}" />
<SolidColorBrush x:Key="ExpanderHeaderTextColor" Color="{StaticResource Color3}" />
<LinearGradientBrush x:Key="headerGradientBrush"

For Arrow Direction Change you can Use ControlTemplate.Triggers in ToggleButton ControlTemplate
<Color x:Key="Color4">Orange</Color>
<SolidColorBrush x:Key="ToggleButtonUpArrowBrush" Color="{StaticResource Color4}" />
<ControlTemplate x:Key="ExpanderToggleButton" TargetType="{x:Type ToggleButton}">
<Grid Width="16" Height="16">
<Path Stroke="{StaticResource ToggleButtonArrowBrush}"
Data="M 3,4 l 5,5 5,-5" />
<Path Stroke="{StaticResource ToggleButtonArrowBrush}"
Data="M 3,7 l 5,5 5,-5" />
<ContentPresenter VerticalAlignment="Center"
HorizontalAlignment="Center"
Content="{TemplateBinding Content}" />
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="true">
<Setter Property="Data" TargetName="arrow1" Value="M 3,9 l 5,-5 5,5"/>
<Setter Property="Data" TargetName="arrow2" Value="M 3,6 l 5,-5 5,5"/>
<Setter Property="Stroke" TargetName="arrow1" Value="{StaticResource ToggleButtonUpArrowBrush}"/>
<Setter Property="Stroke" TargetName="arrow2" Value="{StaticResource ToggleButtonUpArrowBrush}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
And For the Left most Rectangle rather than using a Border use a rectange & use its fill property like
<Style TargetType="Expander">
<Setter Property="Foreground" Value="{StaticResource ExpanderHeaderTextColor}" />
<Setter Property="Template">
<Setter.Value>
<!-- Control template for Expander -->
<ControlTemplate TargetType="Expander">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Name="ContentRow" Height="0" />
</Grid.RowDefinitions>
<!--Header Area-->
<Border Name="Border" Grid.Row="0" BorderBrush="{StaticResource ExpanderBorderBrush}"
BorderThickness="1">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="20" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="20" />
</Grid.ColumnDefinitions>
<!--Rectangle in the header-->
<Rectangle Grid.Row="0" x:Name="LeftPanel" Fill="{StaticResource ExpanderBorderBrush}" Width="10" HorizontalAlignment="Left"/>
<!-- The following puts the toggle button in the right hand column, just like I want! -->
<ToggleButton Grid.Column="2" IsChecked="{Binding Path=IsExpanded,Mode=TwoWay, RelativeSource={RelativeSource TemplatedParent}}" OverridesDefaultStyle="True" Template="{StaticResource ExpanderToggleButton}"/>
<ContentPresenter Grid.Column="1" Margin="5" ContentSource="Header" RecognizesAccessKey="True" />
</Grid>
</Border>
<!--Content Area-->
<Border Name="Content"
Grid.Row="1"
BorderBrush="{StaticResource ExpanderBorderBrush}"
BorderThickness="1,0,1,1"
CornerRadius="0,0,3,3">
<ContentPresenter Margin="4" />
</Border>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsExpanded"
Value="True">
<Setter TargetName="ContentRow"
Property="Height"
Value="{Binding ElementName=Content,Path=DesiredHeight}" />
<Setter TargetName="Border"
Property="BorderBrush"
Value="{StaticResource ExpanderBorderBrush}" />
<Setter TargetName="LeftPanel" Property="Fill" Value="{StaticResource ToggleButtonUpArrowBrush}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Hope this is what you were looking for.

1) Anyone have a decent explantion of how Paths work? I have been researching it and it's still confusing.
2)
I found this example:
<Path Fill="SlateGray"
Data="M 2.5,5 l 10,0 l -5,6 Z" />
which draws a small down-facing arrow. How do you turn it so it's facing up?

I suppose it's easiest to explain how the Path statement works if we take your example.
First of all, let's see what M 2.5, 5 does? This moves the starting point to a point that is at 2.5, 1 relative to the owning container.
Next, l 10, 0 draws a line that starts at the point we specfied above, and ends at the point 10, 0.
Finally, l -5,6 Z draws the path from the point at 10, 0 and ends at -5,6. The Z tells the renderer to close the shape, so a line is drawn to the point that we started off with.

Ok, I got it now.
BTW, is it possible to change a path using a trigger?

Of course it is. You'd have to supply a completely new Data if that's what you were trying to achieve, but it is certainly doable.
|
|
|
|

A path is a geometric representation of a figure.
For e.g M stands for move or startpoint. M or m can both indicate different things. V would mean a vertical line.
This[^] does explain the syntax in little detail - however, using Expression Blend is actually a much easier option to generate paths[^].

In my view I have a data template with a button in it:
<Button x:Name="SelectionToggle"
Command="{Binding SelectionToggleCommand, Mode=TwoWay}"
Grid.Column="1"/>
The output window shows that "SelectionToggleCommand" is not found on the model. How do I properly bind this command to the viewmodel?
Thanks

One of the wonderful thing about WPF is that Command properties can bind to any class that implements ICommand. Typical examples are Josh Smith's RelayCommand or PRISMs DelegateCommand. Suppose that you have RelayCommand, then you would hook it up like this:
private RelayCommand selectionToggleCommand;
public RelayCommand SelectionToggleCommand
{
get
{
if (selectionToggleCommand == null)
{
selectionToggleCommand = new RelayCommand(SelectToggle, CanSelectToggle);
}
return selectionToggleCommand;
}
}
private void SelectToggle(object o)
{
}
private bool CanSelectToggle(object o)
{
return true;
}

I get that much. The problem is that my XAML is in a data template and the message I get says it can't find the command on my data model.
So I need to tell my code to look on the data context, not the model.

Without knowing how and where your DataTemplate is linked in, I can't offer too much other than to say you really need to look at using a RelativeSource to find the element you are interested in to get the DataContext from.
