asp.net - Prevent GridView Cell CssClass from overriding the ItemStyle-CssClass -


i've got checkboxlist names of gridview columns. when check or uncheck box, triggers postback , show_hide_columns sub (shown below). cycles through list , applies "shown" css appropriate columns headerstyle , itemstyle.

that's working fine.

during gridview's rowdatabound, check see if "scheduled pick" field not equal "max_schedule_pick" field. if that's true, set cell's cssclass "scheduled_pick_out_of_sync".

that had been working rather well, too.

here's problem: when have un-checked scheduled pick column (which should apply "hidden" headerstyle.cssclass , itemstyle.cssclass), appropriate scheduled pick cell still gets "scheduled_pick_out_of_sync" cssclass. result hidden header of cells visible , colored. don't want of them shown @ when column supposed hidden.

below, you'll find code. sure appreciate guys give me keep rowdatabound applying cssclass cell when column hidden.

thanks,
rob

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!
