HtmlTable.HtmlTableRowControlCollection Class
Assembly: System.Web (in system.web.dll)
The HtmlTable.HtmlTableRowControlCollection class represents a collection of HtmlTableRow objects for an HtmlTable control. Controls can be added at the end of the collection with the Add method, or at a specified index location in the collection with the AddAt method. Only controls of type HtmlTableRow can be added to the HtmlTable.HtmlTableRowControlCollection collection.
The following code example demonstrates how to create a custom HtmlTable.HtmlTableRowControlCollection that overrides the Add method so that when rows are added to a table, they are always added at the beginning of the table's row collection.
