解决方案
在onready函数中，在grid.startup之后，请执行以下操作:
dojo.connect(grid, "onRowClick", grid, function(evt){
var idx = evt.rowIndex,
item = this.getItem(idx);
// get the ID attr of the selected row
var value = this.store.getValue(item, "ID");
//open a dialog or new window or redirect to new JSP
//to redirect to new jsp, you can set window.location.href to the new url
//to open a new dialog, i suggest using dijit.dialog
//see: http://archive.dojotoolkit.org/nightly/dojotoolkit/dijit/tests/test_Dialog.html
//to open a new window, use window.open

});

I have a code which is working fine and displaying some set of values to me in a grid which is dojox.grid.DataGrid. Now i want to perform some event like when i click on a particular row it will redirect me to a new JSP page. Or will open a window where i can do something. How to do that ? Please help me out. thanks.

解决方案
In your onready function, after grid.startup, do the following:
dojo.connect(grid, "onRowClick", grid, function(evt){
var idx = evt.rowIndex,
item = this.getItem(idx);
// get the ID attr of the selected row
var value = this.store.getValue(item, "ID");
//open a dialog or new window or redirect to new JSP
//to redirect to new jsp, you can set window.location.href to the new url
//to open a new dialog, i suggest using dijit.dialog
//see: http://archive.dojotoolkit.org/nightly/dojotoolkit/dijit/tests/test_Dialog.html
//to open a new window, use window.open
//http://www.pageresource.com/jscript/jwinopen.htm
});
