At this point we've created a basic grid, filled it with data, refined the display of our columns and added event handlers to handle multiselect options. We've used custom cell formatters, used a custom datatype function, and even added and populated a toolbar in the process. Now let's start looking at some things that aren't necessarily jqGrid specific, but incorporate them for use in our grid. How about a search?
jqGrid includes some things for doing data search, that will automatically build modal windows and stuff. But sometimes you want to format things your own way, or incorporate jqGrid for use within an existing interface. One of the advantages for us, using the datatype function, is that we can preprocess our postdata prior to the ajax request.
