In the earlier article we used simple bindings to display string and integer values that were controlled directly by the controls in a window.

When controls update a property that is also the direct source of other bindings, the user interface can update automatically.

The final task for the first example is to set up the Data Context for the controls.

To show the updated data, you will need to understand two-way data binding.

In two-way binding, the user can modify the data through the user interface and have that data updated in the source.

Here, we use the binding property on target control and we specify the element name, path (whatever things you want to update), and mode of binding as shown in the above example. Now, run the application and check if you change the value of the textbox (target), whether it updates the value in slider.

But, if you update the value in text box, then it will not update the slider value.

You can see that the bindings are connecting correctly because all three key controls contain names on loading.

However, if you modify the first or last names, the full name text block does not change.

In your code, we make a class and access it in main we write more lines of code we can simply write if,else five to six lines of code for this purpose.

If i can do one way or two way binding by simple if,else code , why we use it.

However, although the controls are aware that you have changed the First Name and Last Name properties, they do not know that the logic of Full Name is based upon their values.
