Datagrid FilterRow defaults combobox for 0

[tofix]

Hi,

however the combobox uses a data entry with value 0 (as number) as default.
How this can be disabled?

http://jsfiddle.net/xxxe1p79/

With line 31 with 0 as string the combo text of status filter will stay empty by default:
data:[{value:"0",text:'All'},{value:'P',text:'P'},{value:'N',text:'N'}],

With line 31 with 0 as number, the combo shows "All" as default:
data:[{value:0,text:'All'},{value:'P',text:'P'},{value:'N',text:'N'}],

How can I set data with a value of 0 as number while having the combo text empty as default without defining the number as string?

Thanks!

You can define a 'loadFilter' function to convert the 0 value to '0' string.

Code:

loadFilter:function(data){
    return $.map(data, function(item){
        if (item.value == 0){
            item.value = '0';
        }
        return item;
    })
}

Or clear the inputing box when loaded data successfully.

Code:

onLoadSuccess:function(){
    $(this).combobox('setText', '')
}
