Grid filter: HTML select drop down to include blanks

Discontinued products Uncategorized discussions

I would like to get the HTML select filter to be able to filter for blank values. Currently, in IE and Firefox, blank values seem to be ignored when collecting values to put into the select box. In Chrome, they ARE included. I would like the Chrome behavior in IE and Firefox too.



Thanks,



Note that I have amended the HTML select on the grid filter to use “All” rather than “” as the default (no filtering) option like so:



dhtmlXGridObject.prototype._loadSelectOptins=function(t,c){

    var l=this.collectValues©;

    t.innerHTML="";

    t.options[0]=new Option(“All”,"");

    var f=this._filter_tr?this._filter_tr[c]:null;

    for (var i=0;i<l.length;i++)t.options[t.options.length]=new Option(f?f(l[i]):l[i],l[i]);

};

Hello, that doesn’t work for getting the blank value into the select box.
