datatrigger

In WPF, what are some good approaches to debug a trigger such as this? <Trigger Property="IsMouseOver" Value="True"> <Setter Property="FontWeight" Value="Bold"/> </Trigger> Ideally: If the trigger has been hit, I would like a message to be written to the Debug window within Visual Studio; If the trigger is hit, I want Visual Studio to hit a breakpoint in my C# code. Contango There is an excellent article on WPF Mentor by entitled How to debug triggers using Trigger-Tracing (cached version here ). I've used it innumerable times to debug into triggers, it's an amazing technique for anybody that

I have the following data trigger on the ListBoxItems in my Multi-selection ListBox <DataTrigger Value="True"> <DataTrigger.Binding> <MultiBinding Converter="{StaticResource DisableWorkItemConverter}"> <Binding ElementName="MainForm" Path="PickedWorkItemID"/> <Binding Path="Id"/> </MultiBinding> </DataTrigger.Binding> <Setter Property="IsEnabled" Value="False"/> <Setter Property="IsSelected" Value="False"/> </DataTrigger> IsEnabled gets set fine, but IsSelected does not get set. How can I fix that? I tried taking out IsEnabled to see if it was conflicting with IsSelected, but the Item remained

Assuming the binding is right and the image files are where they shuld be, can anyone spot why the image in the xaml below won't change when the trigger evaluates to true? Cheers, Berryl <Image Source="..\..\Images\OK.png" Grid.Column="2" Stretch="None"> <Image.Style> <Style> <Style.Triggers> <DataTrigger Binding="{Binding TimeSheet, Converter={StaticResource overQuotaConv}}" Value="True"> <Setter Property="Image.Source" Value="..\..\Images\Error.png"/> </DataTrigger> </Style.Triggers> </Style> </Image.Style> </Image> Try the following... Set the TargetType="{x:Type Image}" on the Style Change

I'm trying to execute an animation on a cell in a datagrid when the value of the datagrid cell changes. The datagrid itself is bound to an ObservableCollection of plain old CLR objects. In this case lets say the objects are 'Person' objects with properties for 'Firstname', 'Lastname' and 'Age'. The 'Person' class implements the INotifyPropertyChanged interface and each property has the appropriate call to onPropertyChanged in it's setter. This is all fine. In the datagrid definition I've set my DataTemplate for drawing each cell and attached a datatrigger too ... as follows:

I have a TextBox with a style that has a DataTrigger which changes the text, like this: <Grid> <TextBlock Text="Foo"> <TextBlock.Style> <Style BasedOn="{StaticResource TextStyle}" TargetType="TextBlock"> <Style.Triggers> <DataTrigger Binding="{Binding MyBool}" Value="True"> <Setter Property="Text" Value="Bar"/> </DataTrigger> </Style.Triggers> </Style> </TextBlock.Style> </TextBlock> </Grid> But it's not working, the text never changes to "Bar". I have tested using another TextBlock with Text="{Binding MyBool}" and this text changes from "False" to "True". Snoop reveals no errors that I can

Let's say I have the following simple classes: public class Person { public int Id { get; set; } public string Name { get; set; } } public class PersonHolder { public Person CurrentPerson { get; set; } public int ActiveId { get; set; } } Now I have a grid with an instance of class PersonHolder as DataContext , and in the grid I have a StackPanel which is bound to the CurrentPerson of PersonHolder - showing its data: <Grid> <StackPanel x:Name="PersonPanel" DataContext="{Binding CurrentPerson}"> <TextBlock Text="{Binding Id}" /> <TextBlock Text="{Binding Name}" /> </StackPanel> </Grid> So - to
