Rectangle Control in WPF

Rectangle Control in WPF Window Based

Rectangle Means From Latin: rectus "right" + angle A 4-sided polygon where all interior angles are 90° The rectangle, like the square, is one of the most commonly known quadrilaterals. It is defined as having all four interior angles 90° (right angles). The Rectangle object represents a rectangle shape and draws a rectangle with the given height and width. The <Rectangle /> element of  XAML draws a rectangle. The Height and Width attributes represent the height and width of the rectangle. The Stroke and StrokeThickness represents the color and thickness of the rectangle boundary.

Example:

XAML Code:

<Window x:Class="WpfApplication7.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="312" Width="240" Loaded="Window_Loaded">
    <Grid>
     <Rectangle Margin="14,40,0,0" Name="rectangle1" Stroke="Violet" StrokeThickness="9" Height="100" 
     VerticalAlignment="Top" HorizontalAlignment="Left" Width="200" Fill="Pink" RadiusX="6" RadiusY="6" />
    </Grid>
</Window> 

in This code The Fill attributes fill a rectangle with a color. The following code fills a rectangle with pink color.
By setting RadiusX and RadiusY attributes, you can also draw a rectangle with rounded corders.

WrapPanel Control in WPF

WrapPanel Control in WPF Window Based

Wrap panel wraps all child elements to new lines if no space is left. The wrap panel is similar to the StackPanel but it does not just stack all child elements to one row, it wraps them to new lines if no space is left. The Orientation can be set to Horizontal or Vertical.The WrapPanel can be used to arrange tabs of a tab control, menu items in a toolbar or items in an Windows Explorer like list. The WrapPanel is often used with items of the same size, but its not a requirement.

Example:

XAML Code:

<Window x:Class="WpfApplication7.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

UniformGrid Control in WPF

UniformGrid Control in WPF Window Based

The UniformGrid Control arranges content in its area so that all the cells in the grid have the same dimension. It represents a perfect solution if someone prefers to prevent the headache of ordering or arrange controls within an ordinary Grid.

First, the Uniform grid belongs to the System.Windows.Controls. Primitives. It could be found in the tool box at the bottom. A UniformGrid show child elements or control in columns and rows of the same size. Or we can say The number of cells is adjusted to accommodate the number of controls. 

Example:

XAML Code:

<Window x:Class="WpfApplication7.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

ViewBox control in WPF

ViewBox control in WPF Window Based

The Viewbox element automatically scales its content to fill the space available.the Viewbox control, which expands a control to fill the available space (while keeping the aspect ratio) but the control can assume absolute size. The view box could only have one child; else if a view box contains more than one child, an argument exception will be thrown. Viewbox and Viewport are the properties of ImageBursh, DrawingBrush, TileBrush and VisualBrush elements in Windows Presentation Foundation. With these two attributes we can crop images and shapes.

Example of  ViewBox Control In WPF 
 
Real Image:

Slider Control in WPF

Slider Control in WPF Window Based

Slider can be used as a selector for Diffrent values.  These values (which are double) can have a minimum and maximum.  You can put different tick values for these values to split this interval.  On the other hand you can set some values for intervals and delays between movements and clicks on ticks.

Important Properties :

• AutoToolTipPlacement: Specifies if a ToolTip must be shown and where it will be displayed.
• Delay: A value in milliseconds that specifies how long RepeatButton should wait before an  decrease or increase.
• Interval: a value in milliseconds that specifies the time for waiting between repeats.
• LargeChange: The amount that should be added or subtracted to or from Value attribute when user clicks on scrollbar.
• Maximum: Maximum value for slider.
• Minimum: Minimum value for slider.
• Orientation: Gets to values, Horizontal or Vertical and specifies the orientation of slider Control.
• SmallChange: The amount that should be added or subtracted to or from Value attribute when user clicks on thumb.
• TickPlacement: Determines the place that ticks should be placed.
• Ticks: A required attribute and a set of double values for ticks.
• Value: ByDefault selected value for tick.

Syntax Of Slider Control:

<Slider Name="Slider1" Width="200" Height="20"
        Background="Gray" Maximum="80" Minimum="0">           
</Slider> 

In Above Code The Width and Height property represent the width and the height of the control. The Name property represents name of the control, which is a unique identifier of the control. The Background property is used to set the background color of the control. The Minimum and Maximum properties represent the minimum and maximum values of the slider range.

Example:

Original Image:

 

When we increase the slider the image zooms.

ScrollViewer Control In WPF

ScrollViewer Control In WPF Window Based

WPF provides a ScrollViewer control that is a container for other controls and creates a scrollable area. It is simple to create and add to a XAML file. The developer can choose to display a horizontal and/or vertical scroll bar. For this article, I chose to hide the scoll bar so that the user must scroll by clicking on the content in the ScrollViewer..In WPF scrolling or you can say the ScrollViewer is used when we want to fit the large amounts of content in a limited amount of space. The ScrollViewer control provides a convenient way to enable scrolling of content in WPF. ScrollViewer encapsulated the ScrollBars within it and displays it whenever it is required. As the ScrollViewer implements IScrollInfo is the main scrolling area inside the scrollviewer. ScrollViewer also responds to mouse and keyboard commands.

 

Syntax of  ScrollViewer:

<ScrollViewer HorizontalScrollBarVisibility="Visible" >
</ScrollViewer>

Password Control in WPF

Password Control in WPF Window Based

The password box control is a special type of TextBox designed to enter passwords. The typed in characters are replaced by asterisks. Since the password box contains a sensible password it does not allow cut, copy, undo and redo commands.

The PasswordBox control allows you to hide the characters and limit the number of characters to be typed in the editable area. 

 

Properties:

Password property contains the password in the PasswordBox and PasswordChar is the masking character for the password.

Following tag create the Password Box control with the masking character as * and maximum password length of 50 characters.

The MaxLength property is used to get and set the maximum number of characters you can enter in a PasswordBox.
 

Event: To handle the event add the PasswordChanged="Password1_OnPasswordChanged" 

PasswordChanged event is main event of the control and is raised when password property 

has been changed in the xaml and write the handler as

protected void Password1_OnPasswordChanged(object sender, RoutedEventArgs e)
{
     Console.WriteLine(PasswordBox1.Password);
}
