TextBox Control tutorials

  • The TextBox server control is an input control that lets the user enter text. By default, the TextMode   property of the control is set to  TextBoxMode.SingleLine, which displays a single-line text box.

  • You can configure it to be single-line or multiline, or to act as a password entry box, hiding the text being typed in it. If you set it to multiline, it automatically wraps the text it contains unless the Wrap property is set to false. Its Textproperty sets and retrieves the text content within the box. The text it contains can exceed the length of the control displayed on the page, in which case the beginning of the text is scrolled off to the left of the box.

 

Syntax:

The basic syntax of TextBox Control is:

<asp: TextBox ID= “txtname” runat= ”server”></asp:TextBox>
