extjs - How can I give this grid expandable rows? -Ext JS -


i have tried give grid expandable rows. here's code:

ext.define('am.view.metadata.list' ,{     extend: 'ext.grid.panel',     alias: 'widget.metadatalist',     title: '<center>results</center>',     store: 'metadata',      requires: ['ext.*'],         collapsible: true,     dockeditems: [{         xtype: 'toolbar',         dock: 'bottom',         items: [             { xtype: 'tbtext',  text: 'loading...', itemid: 'recordnumberitem'  },             '->',             { text: 'print', itemid: 'print' },             '-',             { text: 'export', itemid: 'export' }         ]     }],     initcomponent: function() {         this.columns = [             {header: 'technical name',  dataindex: 'tech_name', flex: 4, tdcls: 'grid_cell'},             {header: 'kbe id', dataindex: 'kbe_id', flex: 2, tdcls: 'grid_cell'},             {header: 'kbe name', dataindex: 'kbe_name', flex: 3, tdcls: 'grid_cell'},             {header: 'view name', dataindex: 'view_name', flex: 4, tdcls: 'grid_cell'},             {header: 'database/schema', dataindex: 'db_schema', flex: 3, tdcls: 'grid_cell'},             {header: 'privacy', dataindex: 'privacy_indicator', flex: 3, tdcls: 'grid_cell'}         ];          this.callparent(arguments); //calls parent method of current method in order override        } });

and here's instantiate in app.js

{ xtype: 'metadatalist', padding: '5px 5px 5px 5px', height: 430, width: '100%', hidden: true}

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!
