Textblock binding not updating

Anything else I can bind to, or flag I can set on my binding which achieves my goals? As of writing, all properties except for the Text property, is updated as soon as the property changes PropertyChanged , while the Text property is updated when focus on the destination element is lost LostFocus. To see how all of these options work, I have updated the example from the previous chapter to show you all of them: Value is of type String. The third and last TextBox uses the PropertyChanged value, which means that the source value will be updated each time the bound property changes, which it does in this case as soon as the text changes. Due to some evil did I say Legacy code? In the Code-behind, you will find the Click handler, where we use a couple of lines of code to get the binding from the destination control and then call the UpdateSource method on it. I am also a bit unsure of whether your template is associated with an IMyLegacyThingy property of the main object, or a property of an IMyLegacyThingy. You say that binding to Value rather than to Property does trigger a refresh. The data template is being used to present a single property of type IMyLegacyThingy which is a dynamically generated the underlying object implements ICustomTypeDescriptor. Yes, Node also happens to wrap up the logic for invoking the property getter against the data source, but that's really a convenience.

The first one is set to Explicit, which basically means that the source won't be updated unless you manually do it. It defaults to the value "Default", which basically means that the source is updated based on the property that you bind to. The third and last TextBox uses the PropertyChanged value, which means that the source value will be updated each time the bound property changes, which it does in this case as soon as the text changes. The first value doesn't update before you click the button, the second value isn't updated until you leave the TextBox, while the third value updates automatically on each keystroke, text change etc. In the Code-behind, you will find the Click handler, where we use a couple of lines of code to get the binding from the destination control and then call the UpdateSource method on it. Sorry if these are dumb questions! For that reason, I have added a button next to the TextBox, which will update the source value on demand. I am also a bit unsure of whether your template is associated with an IMyLegacyThingy property of the main object, or a property of an IMyLegacyThingy. The first two has already been described, while the last one simply means that the update has to be pushed manually through to occur, using a call to UpdateSource on the Binding. Otherwise, Is there any way you can think of for me to get my custom converter to refresh itself when the Node's Value changes? Now I'm not sure, but I expected that refreshing a property's value woudl trigger a refresh of the Node. It means that the source value will be updated each time the destination control loses focus. As to your problem, I don't think I've understood it fully. The UpdateSourceTrigger property In the previous article we saw how changes in a TextBox was not immediately sent back to the source.

Anything else I can bind to, or flag I can set on my binding which achieves my goals? So much for philosophy. Posted on Jul 15 ivan 5, posts The reason Node doesn't notify of changes is that Node basically packages up two things: For those situations where you need more control of the process, this property will definitely help though. Value is of type String. So why not do that? A Node's basic job is to represent, well, a node in the grid -- a slot, if you like -- and the slot doesn't change. Try running the example on your own machine and see how the three textboxes act completely different:
