Resources are objects referred in WPF XAML. In C# code when we create an object we do the following three steps:-
using CustomerNameSpace; //
import the namespace.
Customer obj = new Customer(); // Create object of the class
Textbox1.text = obj.CustomerCode; // Bind the object with UI elements
So even in WPF XAML to define resources which are nothing but objects we need to the above 3 steps :-
- Import namespace where the class resides: - To define namespace we need to use the "xmlns" attribute as shown in the below XAML code.
Title="MainWindow" Height="350" Width="525">
- Create object of the class :- To create an object of the class in XAML we need to create a resource by using the resource tag as the below code. You can the object name is 'custobj".
The above code you can map to something like this in C#
Customer custobj = new Customer();
- Bind the object with UI objects :- Once the object is created we can then bind them using bindings like one way , two way as explained in "Explain one way, two way, one time and one way to source?".
