c# - Stay in Datagrid edit mode when data is not valid -


i'm new wpf. windows forms , datagridview can force user stay in edit mode if value entered in grid not valid (for example when entering letters in column valuetype set double) code this:

        datagridview grid = new datagridview();         grid.dataerror += (sender, e) => { };

i'm trying have similar behavior wpf datagrid no luck. tried following binding options:

            datagrid.columns.add(new system.windows.controls.datagridtextcolumn() { header = "aheader", binding = new system.windows.data.binding("aproperty") { validatesondataerrors = false, validatesonexceptions = false } });

but can't see change @ all. entering non valid data causes app crash. idea please?

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!
