extjs4.1 - Extjs 4 How to merge 2 similar records into one record -


i have grid, want merge similar records 1 record.

i don't want group record, want merge record

i mean,

{ { firstfield: "record1", commonfield: "abc", fourthfield: "4" }, { firstfield: "record2", commonfield: "abc", fourthfield: "5" }, { firstfield: "record3", commonfield: "abc", fourthfield: "6" } }

so above json u can see there "commonfield" has similar text. have show 1 record instead of 3 records, fourthfield added [4+5+6] final json should become like

{ { firstfield: "record1", commonfield: "abc", fourthfield: "15" }

}

is there way achieve ? summary addition or operation similar can on records ?

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!
