Not a SlickGrid question, technically, but...
Assuming we're starting with something like the filtering example:
http://mleibman.github.com/SlickGrid/examples/example4-model.html
you'll have a function that does the actual filtering like:
<code>
function myFilter(item, args) {
if (args.searchString != "" &&
item["title"].indexOf(args.searchString) == -1) {
return false;
}
return true;
}
<code>
Simply apply 'toLowerCase()' or 'toUpperCase()' to both the search
string and the item.title field and you have case insensitive
filtering.
