How to link items to a UserControl - WPF

In this article we will see how to perform the binding controls within a UserControl to a WPF application.

And accomplish this task using:
  • The DataContext property of the user control.
Reviewing concepts

A UserControl is a control created from existing controls, adding these controls into a single control in order to optimize your code. It is indicated when you realize that there is a loop in the structure of which involved controls so that if you create a composite control, these controls with the data manipulation is facilitated.

Note: Do not confuse a User Control with a Custom Control in WPF. A Custom Control is a control derived from other control and is used when you create a control from the existing one to include a feature that has no existing control.

After the user control is created to use it just do the following:
  • Include a reference to the namespace of the user control, (and if the user control assembly is not in the same assembly);
  • Include the XAML control in the window where we want to use it.
We will see how to perform data binding to a ListBox control used on a UserControl.

Creating a WPF application

Open Visual Basic 2010 Express Edition and create a new application type WPF Application with the name UserControl_Binding.


On the Project menu, click Add New Item and select the template User Control (WPF), then enter the name macLista.xaml.


Note that the model exists Custom Control (WPF) which is different from User Control (WPF).

Then set the following XAML code for this user control that we create:

Download code now (notepad 4kb)

We define a user control with two first ListBox where the Listbox has the property ItemsSource linked to the current DataContext. Specifying Path =. is used to link to the source of current. Specify the Path =. is not required, can also be written like this: ItemsSource = "{Binding}".

The second ListBox gets ItemsSource MeuItemsSource dependency property. ItemsSource Since this property is linked to user control, you must specify the element whose property is linked to the listbox, then we have this way: ElementName = meuUserControl.

The layout of the ListBox control displays two and can be seen below: (Below is the XAML code).



Linking items to the UserControl in our application

Let us now use the UserControl macListBox we create in our application.

Open the file and the XAML code MainWindow.xaml will include the following statements:

Download your code now (notepad 1kb)

As shown below, we see the result of the inclusion of two lines of XAML code above:


Let us now define the file MainWindow.xaml code to use the user control and perform linking of items in the ListBox control.

Change the code MainWindow.xaml XAML file as shown below:


 Now all we have to do and set the data source file MainWindow.xaml.vb as the code below:

Imports System.Collections 
Imports System.Windows
Public Class MainWindow

Private _testaLista The List (Of String)

Public ReadOnly Property TestaLista () As List (Of String)
Get
If _testaLista Is Nothing Then
start ()
End If
Return _testaLista
End Get
End Property

Private Sub start ()
_testaLista = New List (Of String) ()
_testaLista.Add ("Jose Carlos Macoratti")
_testaLista.Add ("Ana Maria Fonseca.")
_testaLista.Add ("Miriam Estela Ribeiro.")
_testaLista.Add ("Jefferson-Day Andre")
_testaLista.Add ("Janice Rachel Smith.")
_testaLista.Add ("Mario Santos")
_testaLista.Add ("Jessica Lang Lima Bueno")
End Sub

End Class 

When we run the project the following happens:

The first user control in the first TabItem binds to TestaLista DataContext of the window.

After the first listbox in the user control is linked to the DataContext that will show the contents of TestaLista.

The result is shown below:


Although the dependency property defined in MeuItemsSource user control, not used in the example. To do so would have to set the user in control for the dependency property as follows:

Imports System.Collections 
Imports System.Windows
Imports System.Windows.Controls

Partial Public Class macLista
Inherits UserControl

Public Shared ReadOnly MeuItemsSourceProperty The DependencyProperty

Shared Sub New ()
macLista.MeuItemsSourceProperty DependencyProperty.Register =
("MeuItemsSource", GetType (IEnumerable), GetType (macLista))
End Sub

Public Property MeuItemsSource () As IEnumerable
Get
Return DirectCast (GetValue (macLista.MeuItemsSourceProperty), IEnumerable)
End Get
Set (ByVal value As IEnumerable)
SetValue (macLista.MeuItemsSourceProperty, value)
End Set
End Property
Sub New ()
End Sub
End Class

Then just set the file MainWindow.xaml another TabItem defined as follows:

Thus we show how to perform the binding in controls created by the user.

Creating a plugin for jQuery


Learn how to create a plug-in for jQuery from scratch - the basics, options, compatibility and examples.

The Basics
A plugin is written as a method or function.

Creating a jQuery function

Syntax
The function must return this.each (..) to maintain the ability to "chaining" - so that the function can be used with one or several objects jQuery.

jQuery.fn.myFunction = function () {
this.each return (function () {
/ / Element-specific code here
});
};


Example

jQuery.fn.makeTextRed = function () {
this.each return (function () {
$ (This). Css ('color', 'red');
});
};
/ / Example usage

$ ('# My-div'). MakeTextRed () / / make text in "my-div" red

$ ('P'). MakeTextRed () / / make all red Paragraphs

Creating a jQuery method

Syntax
jQuery.myMethod = function () {
/ / Code here
};
Example
jQuery.sayHelloWorld = function () {

alert ('Hello World');

};
/ / Example usage

$. SayHelloWorld () / / alerts "Hello World"

Options


Let your plugin more flexible and user friendly as possible, using options. The method $. Extend () takes two or more objects as arguments and combines their contents within the first object.

Example
A function that sets the text color (red by default).

jQuery.fn.makeTextColored = function (settings) {
var config = {
'Color': 'red'
};
if (settings) {$. extend (config, settings);}
this.each return (function () {

$ (This). Css ('color', config.color);

});

};

Now we can choose to use this function passing the parameter settings or not.

$ ('# My-div'). MakeTextColored () / / make red text (default)
$ ('# My-div'). MakeTextColored ('blue') / / make text blue

Compatibility

Because the variable $ can be used by other plugins, use a technique "disguised" to make your plugin compatible future.

(Function ($) {
$. Fn.myFunction = function () {
this.each return (function () {
/ / Element-specific code here
});
};
}) (JQuery);

We went to the jQuery function, and we can now use jQuery for any outfit you want. So, instead of the $, you could use any valid JavaScript variable name.

A checklist of the jQuery plugin
  • This is a list of important points to remember when developing a jQuery plugin ( the jQuery.com ).
  • Name your file jquery. [Insert the plugin name]. Js, eg. jquery.debug.js.
  • All new methods are attached to the object jQuery.fn object, and all functions to the jQuery object.
  • For internal methods, this is a reference to the current jQuery object.
  • Any methods or functions that you attach must have a semicolon (;) at the end - otherwise the code will break when compressed.
  • Your method must return the jQuery object, unless it was explicitly noted otherwise.
  • Use this.each to iterate over the current set of matching elements.
  • Always attach the plugin to jQuery instead of $, so that users can use a custom outfit via noConflict ().
Templates jQuery plugin

These are good code templates to begin developing a jQuery plugin.
Template Function

(Function ($) {
$. Fn.myPlugin = function (settings) {
var config = {
'Foo': 'bar'
};
if (settings) {$. extend (config, settings);}
this.each return (function () {

/ / Element-specific code here

});

};

}) (JQuery);

Template Method

(Function ($) {
$. MyPlugin = function (settings) {
var config = {
'Foo': 'bar'
};
if (settings) {$. extend (config, settings);}
/ / Code here
return this;

};

}) (JQuery);

Example: jQuery Slideshow Plugin

I decided to use very simple examples so far that you might be familiar. The following example is a little more complex and can help you find your inspiration.

He uses the setInterval () together with the effects fadeOut () and fadeIn () jQuery to generate the cycle of any images within a HTML element.

Configuration

HTML


CSS

# Slideshow img {
display: none;
position: absolute;
}

JavaScript

(Function ($) {
$. SimpleSlideShow = function (selector, settings) {
/ / Settings
var config = {
'Delay': 2000,
'FadeSpeed': 500
};
if (settings) {$. extend (config, settings);}
/ / Variables

var obj = $ (selector);

var img = obj.children ('img');

var count = img.length;

var i = 0;
/ / Show first image

img.eq (0). show ();
/ / Run slideshow

setInterval (function () {

img.eq (i). fadeOut (config.fadeSpeed);

i = (i +1 == count)? 0: i +1;

img.eq (i). fadeIn (config.fadeSpeed);

}, Config.delay);
return this;

};

}) (JQuery);


Use

To activate the slideshow div # slideshow, we simply call it using the following JavaScript code:
