who is drake dating now - Wpf label content not updating

The binding is based on the name of the control, so if you change this name, you will also have to remember to change the binding.

The Refresh method is the extension method that takes any UI element and then calls that UIElement's Dispatcher's Invoke method.

The trick is to call the Invoke method with Dispatcher Priority of Render or lower.

The Image control, described later in this tutorial, uses a remote image - this is ONLY for demonstrational purposes and is NOT a good idea for most real life applications.

In most situations, the Label control does exactly what the name implies: It acts as a text label for another control. For most other cases, you should probably use a Text Block control or one of the other text containers that WPF offers.

Text Block controls doesn't support this functionality, but the Label does, so for control labels, the Label control is usually an excellent choice.

Let's look at an example of it in action: The screenshot shows our sample dialog as it looks when the Alt key is pressed.

All my internet searches actually shows how to do this using background thread - it is the approach that needs to be taken in a proper programming context, however there are times when you just want to do something quick & dirty or you want to augment an existing app / port where you don't want to introduce new elements.

There are also considerations to be made when both UI and worker thread access the same data, especially with regard to data binding (see my post about collection change not supporting multi-threading out of the box).

Since we don't want to do anything, I created an empty delegate. When the Dispatcher Priority is set to Render (or lower), the code will then execute all operations that are of that priority or higher. Content to something else, which will result in a render operation. Invoke, the code essentially asks the system to execute all operations that are Render or higher priority, thus the control will then render itself (drawing the new content).

Afterwards, it will then execute the provided delegate (which is our empty method).

Let's try an example where we have both an image and a piece of text inside the Label, while also having an access key for each of the labels: This is just an extended version of the previous example - instead of a simple text string, our Label will now host both and image and a piece of text (inside the Access Text control, which allows us to still use an access key for the label).
