Web Forms Tab, Toolbox

Displays a list of Web server controls and validation controls that you can add to Web Forms. This tab is available only when you are working in Design view of the Web Forms designer.

Note   You can also create HTML server controls on your Web Forms pages by adding elements from the HTML tab of the Toolbox and then converting them to controls. For information on the difference between these controls, see Introduction to ASP.NET Server Controls.

Validation controls allow you to add user input validation to any Web control or HTML control on the Web Forms page.

By default, a Web Forms page uses grid layout mode — that is, elements are arranged using absolute positioning (x and y coordinates). Alternatively, you can use flow layout mode, in which elements are arranged as in a traditional HTML page (top to bottom). For details, see Positioning HTML Elements in Design View.
