This article is the continuation of my last article in Silverlight controls series, read last article here.
TextBox control is used to get input data from the user in Silverlight.

In case we want to specify its value, we specify the "Text" property.
<TextBlock Canvas.Top="15" Canvas.Left="5" Text="Your name : "/>
<TextBox x:Name="TextBoxName" Height="25" Width="100" Canvas.Left="100" Canvas.Top="10"/>
In case we want to display a multi-line textbox so that user can be able to submit large amount of textual data, we can set the height and width properties of the textbox along with TextWrapping to wrap and AcceptReturn to true value. This can be said to be a good thing as one control perfors the role of textbox as well as the teatarea.
TextWrapping allows the text to automatically wrap to the next line in case use keeps writing more content in a single line.
AcceptReturn allows user to press enter key to shift the cursor to next line in the textbox.
<TextBlock Canvas.Top="45" Canvas.Left="5" Text="Your details : "/>
<TextBox x:Name="TextBoxDetails" Height="150" Width="250" Canvas.Left="100" Canvas.Top="45" TextWrapping="Wrap" VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Disabled" AcceptsReturn="True" />
PasswordBox allows us to provide a password box to the user that enables user to submit password. In this textbox, the characters that are entered, appears as masked.
In case we want to prepopulate the password to the Password box, we can set the Password attribute.
In case we want a custom character as the masked character for the Password box, we can set to PasswordChar attribute.
<PasswordBox x:Name="PasswordBox1" Width="160" Height="35" Canvas.Left="20" Canvas.Top="20" BorderThickness="5" Password="MyPassword" PasswordChar="#" />
RichTextBox control allows us to display and edit rich content into Silverlight application. Rich content can include bold, italic, different size text or image.
RichTextControl allows several child controls to format the text in italic, bold and color, it also provide child control to insert image in the RichTextBox control.

Image is used to place the image in the RichTextBox control. Source attribute is used to specify the url of the image. In order to display the image, we need to
<RichTextBox Height="250" Width="250" x:Name="DescriptionBox" Canvas.Top="10" Canvas.Left="10">
This is the simple text.
This<Span FontFamily="Arial" FontSize="18">is a good boy.</Span><LineBreak/><LineBreak/><LineBreak/><LineBreak/><InlineUIContainer><Image Source="../Images/itfunda.jpg" Stretch="Uniform" Width="150" Height="100" /></InlineUIContainer></Paragraph>

If we want to add
BOLD content, we can use Bold class like below.
Response.Write(Date.ToShortDateString());Bold b = new Bold();
b.Inlines.Add("This text is in bold");Paragraph p = new Paragraph();
