String Date to ExtJS Date Formatted

[harman]

Hi,

I have a Date field that comes to me as a String in JSON like

"09-05-2012 7:33 AM"

I have to show it as a Date with the same format in my Grid column.
(I am converting it to date as grid column does not sort it as Date but String)
How do i do it?
If i do this in my model

{name: 'someDate', type: 'String', convert:function(value, records){                 var rcptDate=new Date(value);
                 return Ext.Date.format(rcptDate, 'm-d-Y g:i A');
             }}

i get value like NaN-NaN-0NaN 12:NaN PM

What am i doing wrong?
Or is it that it cant be converted?

You can define the field in the store as follows:

{
    name: 'someDate',
    type: 'date',
    dateFormat: 'm-d-Y g:i A'
}

and then put the following renderer on your grid column:

renderer: Ext.util.Format.dateRenderer('m-d-Y g:i A')

I would also use the date type for the field as droessner stated, but I would be slightly more lazy and use the datecolumn

Thanks droessner,

Exactly what i wanted.
However i will need a little more testing to see if the Sorting works correctly.
