TableHeaderRow Class
Assembly: System.Web (in system.web.dll)
The TableHeaderRow class represents a heading row in a Table control. This class supports displaying tables on devices with a limited screen size. On these devices, a table with many columns and rows must be rendered across multiple pages. Adding a TableHeaderRow to a Table control allows you to specify a heading row that is rendered as the first row on each page that displays a view of the table. For more information about the view formats for a table rendered on a device with a limited screen size, see Table.
A TableHeaderRow object can contain only TableCell objects. To add content to the TableHeaderRow, you must add one or more TableCell objects to the row. Then, set the Text property of each TableCell object in the row to specify the contents of each cell. Alternatively, you can add a control to a TableCell object to specify its contents.
You can programmatically manage the cells in the TableHeaderRow by using the Cells collection. The Cells collection is a collection of TableCell objects that represent the cells in the row.
The TableHeaderRow inherits properties from TableRow that allow you to control how the contents in the row are displayed. For example, you can use the HorizontalAlign and VerticalAlign properties to specify the alignment of the contents.
The following code example demonstrates the declarative syntax for creating a Table control that has a TableHeaderRow and a TableFooterRow.
