Text

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"/>

TextWrapping, AcceptReturn

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" />

Output

PasswordBox

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.

Password

In case we want to prepopulate the password to the Password box, we can set the Password attribute.

PasswordChar

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="#" /> 

Output

How to add content to the RichTextBox control dynamically from code behind?

If we want to add BOLD content, we can use Bold class like below.

Code

Response.Write(Date.ToShortDateString());

Bold b = new Bold();

b.Inlines.Add("This text is in bold");

Paragraph p = new Paragraph();

p.Inlines.Add(b);

DescriptionBox.Blocks.Add(p);
