HTML select filters on grid

Discontinued products Uncategorized discussions

Hi,



Using the HTML select filters, currently the blank entry means “no filtering”. Is it possible to change this so we have a dummy “All” value instead, and have the blank entry really mean “those rows where the value of the cell is actually blank”?



Thanks,

Is it possible to change this so we have a dummy “All” value instead

Can be done only by code modification
dhtmlxgrid_filter.js
dhtmlXGridObject.prototype._loadSelectOptins=function(t,c){
var l=this.collectValues©;
t.innerHTML="";
t.options[0]=new Option("","");

can be replaced with

t.options[0]=new Option(“All”,"");

>>and have the blank entry really mean “those rows where the value of the cell is actually blank
mygrid.attachEvent(“onFilterStart”,function(a,b){
if (a[INDEX]==”") a[INDEX]=function(val){ return val==""; }
return true;
});
where INDEX - index of column in which select filter used
