Your post indicates that you want to write a tutorial to help others use jqGrid or the like. Is that really what you want to do? If so then what's the actual question? If not then I assume that what you're actually asking for is for us to direct you to a tutorial that already exists to help you use jqGrid. Is that it?
all I wanted to need to refer me comprehensive /understandable tutorial or plugin (if some body know)..so that I can bind data to it ..like asp.net datagrid ..as I did not find yet
Are you talking about jqGrid specifically or some other jQuery plugin? Regardless, you can't bind data to it like you can ASP.NET server controls. It's a jQuery plugin and jQuery is a JavaScript library so you work with it in JavaScript code.
