Grid object inizialization

When you declare a Grid type object, the main ErgoDataGrid component, all the not read-only parameters which determine the ErgoDataGrid look-and-feel, its behaviors and its data interface, listed in the reference page, are passed to its initialization procedure.

Next example shows the initialization procedure for the Cars object:

- utilized files are two:

the first one is a Javascript file called "Cars.js", containing the function Cars_init(), in which an ErgoDataGrid instance has to been declared;

the second file is "demo.htm", in which needed files to makes appear the grid to the final user are reported through <SCRIPT> and <LINK> tags; you have to make attention to where the <SCRIPT> tag with its src equal to "Cars.js" is declared: ErgoDataGrid appears just in corrispondence of this tag, when Visits.Show() method is called.
