c# - WPF: Custom routed event with extra information -

-

I have a normal WPF window, let's call it TopLevel , in which one The bunch is, among other things, in a simple ListView , some events should be logged in various elements in the application.

It looks like I have a group of user controls called grid in TopLevel which contains work each , there is an object with them, let's call it a order , as well as a standard checkbox.

Now whenever a user checks a checkbox in work , but command objects in the event also top level Should be included, so I can work from TopLevel to keep it in the event log.

How can I do this? I'm guessing that I want to use the rooted event for this, but I did not know how to get the "code" to order the "code" in the check box, call it TopLevel < / Code>.

How to do something like this ... 

  Private Zero checkbox Checked (Object Sender, Routing Avent ARG E) {Sendbox as Checkbox = Checkbox; Job Task = FindPartTkS (Checkboxes); Order order = task.order; }

Because you need to cross the visual tree to work, so you can try some recurring ... 

  public framework Element FindParentTask (framework element element) {if (element.Parent.GetType () == Type (Task)) return element. Parents as FrameworkElement; And again FindParentTask (FrameworkElement as element.Parent); }

I have tested this method to retrieve the parent extension to the check box on one of my user controls, it has several levels of visual tree, the stack Nested dock panels in a pile of pans, grids and stacks, have a cure.

c# - TypeConverter in propertygrid only converts from string, not to -

When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
