I’ve encountered this a couple times and keep forgetting what causes it. I ran into this when I renamed the namespace on my code behind file but not in my XAML. So check if you’ve done the same. The namespace and class names need to match since they are both part of a partial class … Read more
You can further simplify the accepted answer. Instead of typing out the enums as strings in xaml and doing more work in your converter than needed, you can explicitly pass in the enum value instead of a string representation, and as CrimsonX commented, errors get thrown at compile time rather than runtime: ConverterParameter={x:Static local:YourEnumType.Enum1} <StackPanel> … Read more
A StaticResource will be resolved and assigned to the property during the loading of the XAML which occurs before the application is actually run. It will only be assigned once and any changes to resource dictionary ignored. A DynamicResource assigns an Expression object to the property during loading but does not actually lookup the resource … Read more
To exit your application you can call System.Windows.Application.Current.Shutdown(); As described in the documentation to the Application.Shutdown method you can also modify the shutdown behavior of your application by specifying a ShutdownMode: Shutdown is implicitly called by Windows Presentation Foundation (WPF) in the following situations: When ShutdownMode is set to OnLastWindowClose. When the ShutdownMode is set … Read more
If you want to bind to another property on the object: {Binding Path=PathToProperty, RelativeSource={RelativeSource Self}} If you want to get a property on an ancestor: {Binding Path=PathToProperty, RelativeSource={RelativeSource AncestorType={x:Type typeOfAncestor}}} If you want to get a property on the templated parent (so you can do 2 way bindings in a ControlTemplate) {Binding Path=PathToProperty, RelativeSource={RelativeSource TemplatedParent}} … Read more
There really is only one name in XAML, the x:Name. A framework, such as WPF, can optionally map one of its properties to XAML’s x:Name by using the RuntimeNamePropertyAttribute on the class that designates one of the classes properties as mapping to the x:Name attribute of XAML. The reason this was done was to allow … Read more
I’m assuming that’s an ARGB code… Are you referring to System.Drawing.Color or System.Windows.Media.Color? The latter is used in WPF for example. I haven’t seen anyone mention it yet, so just in case you were looking for it: using System.Windows.Media; Color color = (Color)ColorConverter.ConvertFromString(“#FFDFD991”);
Here is a very good article regarding the Mutex solution. The approach described by the article is advantageous for two reasons. First, it does not require a dependency on the Microsoft.VisualBasic assembly. If my project already had a dependency on that assembly, I would probably advocate using the approach shown in another answer. But as … Read more
I just had the same problem. Visual Studio isn’t building the project that’s being referenced. Written Instructions: Right click on the solution and click Properties. Click Configuration on the left. Make sure the check box under “Build” for the project it can’t find is checked. If it is already checked, uncheck, hit apply and check … Read more
