An HTTP header consists of its case-insensitive name followed by a colon ':', then by its value (without line breaks).
Leading white space before the value is ignored. In the code-behind write the following code: Code-behind. To display data in The GridViw use a DataAdapter object to retrieve the data from the database and place that data into a table.
The symbol> element is used to define graphical template objects which can be instantiated by a element. The use of symbol elements for graphics that are used multiple times in the same document adds structure and semantics.
