Hi,

You can find the online version of the production documentation here:

The same contents are also offline as a .chm file on your local machine. You can go to Start -> All Programs -> EO.Web Controls 2008 -> EO.Web Controls for ASP.NET 1.1/2.0 -> Documentation.

In order to populate a second grid, you will need to:

1. Respond when an item is selected in the first Grid. There are a number of ways to do this. One way is to handle the Grid's ClientSideOnItemSelected with JavaScript. You can find a sample on how to use this feature at here:

http://www.essentialobjects.com/Demo/Default.aspx?path=Grid\_i1\_i11

2. The above sample changes the innerHTML of a DIV element to display some information when an item is selected. You will need to change that to populate the second Grid. Populating the second Grid is no different than the populating the first one, except that you must populate it on the server side, while your ClientSideOnItemSelected handler is on the client side. Thus you need to use a CallbackPanel to trigger an AJAX call to the server side. You would do this by calling eo_Callback global function. The whole sample project uses this method to load demos. For example, when you select a node in the TreeView on the left side, it calls eo_Callback to trigger an AJAX callback to the server, which then load the corresponding demo on the right side;

For detailed information about populating the Grid or triggering an AJAX Callback, please refer to the documentation for those two controls. You will also want to go over this topic if you are not already familiar with our client side JavaScript interface:
