jquery - datagrid column formatter not working -


i'm using jquery easyui datagrid present data user. i'm trying color data in columns of datagrid based on condition. did this:

$('#my_datagrid_id').datagrid({      columns:[[         {field:'qty', title:'quantity', formatter:function(val, row, idx){              if (val < 25){                 return '<span style="color:red;">('+val+')</span>';             } else {                 return val;             }                         }}     ]]  });

but reason, values of costs less 25 not colored red in datagrid. idea why code not working please?

{field:'qty', title:'quantity',editor:{type:'numberbox'}, formatter:function(val, row, idx){

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
