jqgrid search popup allows all filters to be removed!
I'm trying out very simple search popup on the JqGrid. Please see the code below. There are few issues:
The popup comes up with AND/OR and [+] controls at the very top. See screenshot below: (from FF 4)
You can click on [-] button to remove the very first (and only) filter row. It shouldn't be allowed. First filter row should never be allowed to be removed.
Code:

I suggest to overwrite the internal reDraw method used by filtering (see my another answer for more description). To do this you should include in the searchOptions which you use the beforeShowSearch event handler with the following implementation:
beforeShowSearch: function($form) {
var searchDialog = $form[0],
oldrReDraw = searchDialog.reDraw, // save the original reDraw method
doWhatWeNeed = function() {
$('input.delete-rule:first',searchDialog).unbind('click');
// set fucus in the last input field
setTimeout(function() {
// set fucus in the last input field
$('input[type="text"]:last',searchDialog).focus();
}, 50);
}
searchDialog.reDraw = function() {
oldrReDraw.call(searchDialog); // call the original reDraw method
doWhatWeNeed();
}
doWhatWeNeed();
}
You can see the corresponding demo here.
