Hi
Any help would be very appreciated.
i have a listbox defined in the MainPage.xaml which a bind to a collection of nested objects (boxes).
<ListBox x:Name="MyListBox"
ItemTemplate="{StaticResource NestedDataTemplate}"/>
The box:
public class Box
{
public string BoxName { get; set; }
public ObservableCollection<Box> Boxes { get; set; }
}
I fill each child collection of each box with a single box and I do that up to 15 times, so that the hierarchy contains up to 15 levels.
Box -Box --Box ---Box
...... 15 times
In the handler of the loaded event of the MainPage.xaml.cs the collection is populated like so:
ObservableCollection<Box> boxCollection = new ObservableCollection<Box>();
Box lastBox = new Box();
lastBox.BoxName = "Box Nr. 1";
lastBox.Boxes = new ObservableCollection<Box>();
for (int i = 1; i < 15; i++)
{
Box newBox = new Box();
newBox.BoxName = "Box Nr. " + (i + 1);
newBox.Boxes = new ObservableCollection<Box>();
newBox.Boxes.Add(lastBox);
lastBox = newBox;
}
boxCollection.Add(lastBox);
MyListBox.ItemsSource = boxCollection;
The listbox's items template is a hierarchical data template defined in the resource section of App.xaml.
<sdk:HierarchicalDataTemplate x:Key="NestedDataTemplate">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Border Grid.RowSpan="2" Background="LightGray" Opacity="0.5"/>
<TextBlock Text="{Binding BoxName}"/>
<ListBox Grid.Row="1" ItemsSource="{Binding Boxes}" ItemTemplate="{StaticResource NestedDataTemplate}"/>
</Grid>
</sdk:HierarchicalDataTemplate>
When I run the app, it crashes and throws the following exception which can be investigated in the Application_UnhandledException handler in the App.xaml.cs.
The exception:
Error HRESULT E_FAIL has been returned from a call to a COM component.
at MS.Internal.XcpImports.CheckHResult(UInt32 hr)
at MS.Internal.XcpImports.FrameworkElement_MeasureOverride(FrameworkElement element, Size availableSize)
at System.Windows.FrameworkElement.MeasureOverride(Size availableSize)
at System.Windows.FrameworkElement.MeasureOverride(IntPtr nativeTarget, Single inWidth
Note: If I reduce the amount of hierarchy layers of the box collection, everything works fine.
Please help, I have been struggling for several days. I cannot find anything in forums or blogs.
Thank you

It should be reasonably obvious you are running up against a limitation of the tool, possibly unpublished. Try using a treeview, it is the control designed to do this type of job.

I am implementing a Alerts Section Like This[^] in my application's Dashboard.
All or some of the text can be a hyperlink, with different commands bound to the links. The content of the messages will be automatically generated.
My first thought was have a table like this:
ImageName MessageDate Message ================================================================================================================
vehicle.jpg 2014-05/06 Vehicle Ford F150 Serial # ^L^256565^L^ has maintenance item ^L^Oil Change^L^ ready.
So it would look like:
"Vehicle Ford F150 Serial # 256565 has maintenance item Oil Change ready."
Clicking the serial # would open the vehicle screen. The Oil Change link would open the Maintenance screen.
I would then need to include in the message an action for each link. Like the link symbol, I could follow it with an enum item to denote what type of screen to open. And I would also need the PK's in there also.
Then, when the dashboard item is loaded, it would use a flow panel with both text and links in the data template so the Message column can wrap.
All this is fine, but it feels weird. Anyone done anything like this? Anyone got a better approach?
Thanks

Kevin Marois wrote: an action for each link
Exactly, but it seems that you just happened to use the correct word. System.Action is the class to use, or (more typical in WPF) a Command object (take a look at the Command Pattern). When the link is clicked, you call the Invoke() method of the Action object.

Hi ,
I am currently developing an application but I need to have to switch between two languages , but I can't do it .
In fact , I created two Resources files for both languages and I set them to public and then then I put the propertie to Static as mentioned in many tutorials .
Thank you so much for your help.
My code written :
App.xaml.cs
public App()
{
if (Presentation.ViewModels.LoginWindow.LanguageSelect != null)
{
if (Presentation.ViewModels.LoginWindow.LanguageSelect.Equals("Italian"))
{
System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("it-IT");
}
else
{
System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("fr-FR");
}
}
else
{
Console.WriteLine("Verify the choosig langa=uage!");
}
}
ViewModel:
private string selectedLanguage;
public static string LanguageSelect;
public string SelectedLanguage
{
get
{
return selectedLanguage;
}
set
{
selectedLanguage = value;
RaisePropertyChanged("SelectedLanguage");
LanguageSelect = selectedLanguage.ToString();
}
}
And I the view.xaml
<ComboBox x:Name="MyCombo" Height="23" Width="90" HorizontalAlignment="Right" ItemsSource="{Binding Languages}" SelectedItem="{Binding SelectedLanguage, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" VerticalAlignment="Top" Margin="20" IsEditable="False" Background="DarkCyan" Foreground="Blue"></ComboBox>

I have a treeview bound to a collection of Employees. Each Employee has one or more HoursWorked entity in a property called HoursWorked.
The HierarchicalDataTemplate has an Add button in it to add a new Hours Worked node under it.
Each hours worked node DataTemplate has a Remove button next to it. When it's clicked I'd like to pass both the Employee and the HoursWorked entity.
So I have:
<!--Employee-->
<HierarchicalDataTemplate DataType="{x:Type models:WorkDoneEmployeeInfoModel}"
ItemsSource="{Binding HoursWorked}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="60"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0"
Text="Employee:"
VerticalAlignment="Center"
FontWeight="Bold"/>
<TextBlock Grid.Column="1"
VerticalAlignment="Center"
Text="{Binding EmployeeName}"/>
<Button Grid.Column="2"
Command="{Binding RelativeSource={RelativeSource AncestorType={x:Type UserControl},Mode=FindAncestor},Path=DataContext.AddHoursCommand}"
CommandParameter="{Binding}"
VerticalAlignment="Center"
Height="22"
Width="22"
Margin="10,3,3,3">
<Image Source="/FMG.UI.WPF.Shared;component/Media/Images/add_256.png"
Height="16"
Width="16"/>
</Button>
</Grid>
</HierarchicalDataTemplate>
<!--Hours Worked-->
<DataTemplate DataType="{x:Type models:WorkDoneHoursWorkedModel}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="100"/>
<ColumnDefinition Width="250"/>
<ColumnDefinition Width="100"/>
<ColumnDefinition Width="250"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0"
Text="Time In:"
VerticalAlignment="Center"
FontWeight="Bold"/>
<TextBlock Grid.Column="1"
VerticalAlignment="Center"
Text="{Binding WorkStartDateTime}"/>
<TextBlock Grid.Column="2"
VerticalAlignment="Center"
Text="Time Out:"
FontWeight="Bold"/>
<TextBlock Grid.Column="3"
VerticalAlignment="Center"
Text="{Binding WorkEndDateTime}"/>
<Button Grid.Column="3"
Command="{Binding RelativeSource={RelativeSource AncestorType={x:Type UserControl},Mode=FindAncestor},Path=DataContext.SubtractHoursCommand}"
VerticalAlignment="Center"
Height="22"
Width="22"
Margin="10,3,3,3">
<Button.CommandParameter>
<MultiBinding Converter="{StaticResource MyMultiConverter}">
<!--The EmplyeeEntity-->
<Binding Path=""/> <===== WHAT GOES HERE? ===========
<!--The HoursWorked entity-->
<Binding Path="{Binding}"/>
</MultiBinding>
</Button.CommandParameter>
<Image Source="/FMG.UI.WPF.Shared;component/Media/Images/subtract_256.png"
Height="16"
Width="16"/>
</Button>
</Grid>
</DataTemplate >
So in the bottom template, I am passing the WoursWorked entity, but how do I set up the XAML to pass the parent node?
Thank you
[EDIT - RESOLVED]
<Button.CommandParameter>
<MultiBinding Converter="{StaticResource multiValueConverter}">
<Binding RelativeSource="{RelativeSource AncestorType={x:Type TreeViewItem}, AncestorLevel=2}"/>
<Binding RelativeSource="{RelativeSource AncestorType={x:Type TreeViewItem}, AncestorLevel=1}"/>
</MultiBinding>
</Button.CommandParameter>

I have a DP called FullName. When it changes, I need to parse it and add it to an instance property of type List<<string>> FileAsOptions.
So, when I have
"Joe Smith"
or
"Smith, Joe"
they both get added to the list property.
The FullName property is a DP, and the FileAsOptions is an instance property. It's not a DP because I don't want it to be bindable.
So the FullName DP's change callback calls a private method that parses the name and add it to the instance list
The problem is that the instance property needs to call RaisePropertyChanged, which only works on instance properties. So the property cannot be static.
Here's the code:
public partial class ContactCard : _UserControlBase
{
public ContactCard()
{
InitializeComponent();
LayoutRoot.DataContext = this;
}
private List<string> _FileAsOptions;
public List<string> FileAsOptions
{
get { return _FileAsOptions; }
set
{
if (_FileAsOptions != value)
{
_FileAsOptions = value;
RaisePropertyChanged("FileAsOptions");
}
}
}
public string FullName
{
get { return (string)GetValue(FullNameProperty); }
set { SetValue(FullNameProperty, value); }
}
public static readonly DependencyProperty FullNameProperty = DependencyProperty.Register(
"FullName", typeof(string), typeof(ContactCard),
new FrameworkPropertyMetadata("", new PropertyChangedCallback(OnFullNamePropertyChanged)));
private static void OnFullNamePropertyChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
{
var card = sender as ContactCard;
}
private void setFileAsOptions(string fullName)
{
FileAsOptions = new List<string>();
if (!string.IsNullOrEmpty(fullName))
{
string[] words = fullName.Split(' ');
if (words.Length == 1)
{
FileAsOptions.Add(words[0]);
}
if (words.Length == 2)
{
FileAsOptions.Add(string.Format("{0} {1}", words[0], words[1]));
FileAsOptions.Add(string.Format("{0}, {1}", words[1], words[0]));
}
}
}
}
In summary, I need to be able to call the setFileAsOptions from the DP, which is static.
What's the right approach here?

Unless I've misread your question, it's quite simple! 
private static void OnFullNamePropertyChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
{
var card = sender as ContactCard;
card.setFileAsOptions((string)e.NewValue);
}

I am creating a user control. I will be using this user control in a few different apps. Once it's done I'll include its assembly in my project, reference it, and use it in my XAML somewhere. Pretty standard.
The question is... How do I apply a different set of styles to it based on the app I'm in?
Thanks

The simplest way to achieve this is to have application level themes. In other words, in App A - you would set the styles for your control to be the ones you want in App A; in App B you set the styles for the control based on the ones you want in App B, and so on. Make sure you have a default theme for your control in place as well.

Ok, so create a theme. Isn't a theme just a collection of styles?

Hi Kevin,
Sorry for late reply to your post.
1.You can create a seperate styles for appA, Appb... and apply the theme accordingly as a staticresource.
2.Suppose in same application you want different theme based on some action then just use the above mentioned idea and apply themes using Dynamicresource.
Thanks.

I don't know why I can't get this to work...
In class A I have
public delegate void LoggingDelegate(string message);
and
public void LogMessage(string message)
{
}
then I want to pass it to class B, so I have:
LoggingDelegate logMessageHandler = LogMessage;
ClassB.SomeMethod(logMessageHandler);
Then in ClassB I have
public void SomeMethod(Delegate logDelegate)
{
logDelegate.
}
WHat's wrong here?
Thanks!

All ClassB.SomeMethod knows is that logDelegate is a Delegate, not that it is LoggingDelegate.
At least the way you have shown it.
So the IntelliSense knows only that as well.

I am trying to hide a text block. When a Checkbox is checked, it should be hidden. When it's unchecked the textblock should be visible.
The checkbox is bound to an object called SelectedProcess. If SelectedProcess is null, the textblock should be hidden.
Here's my XAML:
<CheckBox IsChecked="{Binding SelectedProcess.Enabled}"
IsEnabled="{Binding AllowProcessEdit}"
x:Name="EnabledCheckbox"
Foreground="Black"
FontSize="12"
Margin="10,0,0,0"
VerticalAlignment="Center"
HorizontalAlignment="Stretch"/>
<TextBlock Grid.Row="4"
Foreground="Red"
FontWeight="Bold"
FontSize="12"
VerticalAlignment="Center"
HorizontalAlignment="Right"
Text="This process is disabled"
Margin="10,0,0,0">
<TextBlock.Style>
<Style>
<Style.Triggers>
<DataTrigger Binding="{Binding SelectedProcess}" Value="Null">
<Setter Property="UIElement.Visibility" Value="Hidden"/>
</DataTrigger>
<DataTrigger Binding="{Binding SelectedProcess.Enabled}" Value="True">
<Setter Property="UIElement.Visibility" Value="Hidden"/>
</DataTrigger>
<DataTrigger Binding="{Binding SelectedProcess.Enabled}" Value="False">
<Setter Property="UIElement.Visibility" Value="Visible"/>
</DataTrigger>
</Style.Triggers>
</Style>
</TextBlock.Style>
</TextBlock>
It works when SelectedProcess is NOT null, but when SelectedProcess IS null, the text is still visible.
What am I doing wrong here?
Thanks

Your issue seems fixed, which is great.
However, I wonder why you use datatriggers to accomplish this.
Consider doing it through binding instead with the help of a converter.
If the visibility of the texblock is always directly related to the checkbox being checked / unchecked, then you could use elementbinding to do so.
<TextBlock Visibility="{Binding IsChecked, Converter={StaticResource boolToVisibilityConverter}, ElementName=CheckBoxName}" />
The resulting XAML is simpler and achieves the same result.

I'm trying set focus to a UI element from within a view model.
First, following this example[^] I created the Attached Property.
Then in my VM I created a bool property called "IsHourlyMinutesFocused":
private bool _IsHourlyMinutesFocused;
public bool IsHourlyMinutesFocused
{
get { return _IsHourlyMinutesFocused; }
set
{
if (_IsHourlyMinutesFocused != value)
{
_IsHourlyMinutesFocused = value;
RaisePropertyChanged("IsHourlyMinutesFocused");
}
}
}
Next, I added it to the XAML:
<TextBox Grid.Row="0"
Grid.Column="2"
VerticalAlignment="Center"
classes:FocusExtension.IsFocused="{Binding IsHourlyMinutesFocused}"
Focusable="True"
Text="{Binding SelectedProcess.ProcessSchedule.HourlyMinutes}"
Margin="2,0,2,0"
Width="40"/>
When I set IsHourlyMinutesFocused = true, nothing happens. The OnIsFocusedPropertyChanged event in the DP never fires.
What's wrong here?

Hi ,
I am new in coding WPF MVVM apps.
My question is how to change le language using a combobox at Runtime.
I tried the static resources and it worked well , but trying to change it Runtime using Threading.thread class didn't work.
Is there any possibility to solve that problem.
Thanks a lot for your help.

This is now the FOURTH time you have asked the same question. 
DO NOT repost the same question. It won't get your question answered any quicker; if anything, it will just annoy the people who would otherwise be trying to help you, and result in all of your questions being ignored.
