ASP: Text Boxes

asp dot net hosting
ASP: Text Boxes   Text box controls are typically used to accept input from the user. A text box control can accept one or more lines of text depending upon the settings of the TextMode attribute. One of the main features of Web pages is to offer forms that user can use to submit info. A flexible feature is the textmode control to allow a change in the text behavior for things like passwords. Label controls provide an easy way to display text which can be changed from one execution of a page to the next. If you want to display text that does not change, you use the literal text. Basic syntax of text control:
<asp:TextBox ID="txtstate" runat="server" ></asp:TextBox>
Common Properties of the Text Box and Labels:
