dtatgrid dropdowns when typing words autofill is not working, and number formatting is not working

Answer 1

for the problem with the number formatting I found this solution:
<script type='text/javascript'>
$('#tt').datagrid({
...
{field:'amount',title:'Amount',groupSeparator:,sortable:'true',width:100,
formatter:function(value,row,index) {
if(row.amount) {
return number_format(value,2,',','.');
}
}
}
...
}
...
function number_format(num,dig,dec,sep) {
x=new Array();
s=(num<0?"-":"");
num=Math.abs(num).toFixed(dig).split(".");
r=num[0].split("").reverse();
for(var i=1;i<=r.length;i++){x.unshift(r[i-1]);if(i%3==0&&i!=r.length)x.unshift(sep);}
return s+x.join("")+(num[1]?dec+num[1]:"");
}
...
</script>
