TextBoxes in C#

•Text boxes should be used whenever you want users to enter text that you have no knowledge of at design time.

•The primary function of a text box is for users to enter text, but any characters can be entered.

TextBox Properties

•CharacterCasing A value indicating whether the TextBox changes the case of the text entered. 

• Three values are possible:
– Lower: All text entered is converted to lowercase.
–Normal: No changes are made to the text.
–Upper: All text entered is converted to uppercase.

• MaxLength: A value that specifies the maximum length, in characters, of any text entered into the TextBox.

• ReadOnly: A Boolean indicating whether the text is read-only.

• Multiline: Indicates whether this is a multiline control, meaning it is able to show multiple lines of text. When Multiline is set to true, you’ll usually want to set WordWrap to true as well.

• PasswordChar: Specifies whether a password character should replace the actual characters entered into a single-line TextBox. If the Multiline property is true, then this has no effect.

• ScrollBars: Gets or sets which scroll bars should appear in a multiline TextBox control.

• Text: Gets or sets the current text in the TextBox.  

• TextAlign: Gets or sets how text is aligned in a TextBox control.

• SelectedText: The text that is selected in the TextBox.

• SelectionLength: The number of characters selected in the text.

• SelectionStart: The start of the selected text in a TextBox.

• WordWrap: Specifies whether a multiline TextBox should automatically wrap words if a line exceeds the width of the control.
