Is there any difference between WPF TextBlock and TextBox?

Question

What criteria must I consider when selecting one of these two controls?

Answer 1

Common to both TextBlocks and TextBoxes:

• Can be used to display text
• Can be set to specific Height and Width or be set to Auto so that they grow in size with the text.
• Can set font size, font type, font styling, to wrap and to range left, right or centred.
• Can have opacity set and have Pixel Shaders applied.

TextBlock:

• Used for displaying text more focused typographically.
• Can contain text set to different colors, fonts and sizes.
• The line height can also be increased from the default setting to give more space between each line of text.
• Text inside a TextBlock cannot be made selectable by the user.

TextBox:

• Used for displaying text more focused for content input or when content is needed to be made selectable by the user.
• Can only be set to one colour, one font size, one font type etc.
• Have fixed Line Spacing.
• Can also be set to a fixed height and width but also have scrollbars switched on to allow content to expand.
