How can I apply correctly a radio button in a grid extjs? -


i working locally. used function display radio button inside grid, , call function in renderer. know it's wrong, show want.

i don't know how apply radio button work each row.

i use extjs 3.4.

sorry english , disorder.

this array:

var data_metas =    [['ingrese meta n°1','','','','','','100%','100%'],                      ['ingrese meta n°2','','','','','','100%','100%'],                      ['ingrese meta n°3','','','','','','100%','100%']];

this arraystore:

var store_grid_metas = new ext.data.arraystore({                   fields: [                      {name: 'meta'},                      {name: '100%'},                      {name: '75%'},                      {name: '50%'},                      {name: '25%'},                      {name: '0%'},                      {name: 'ponderación'},                      {name: 'nota final'}                   ] });  store_grid_metas.loaddata(data_metas);

the "radiogrid" function:

function radiogrid (value) { return "<input type='radio' name = 'primaryradiometauno' " + (value ? "checked='checked'" : "") + ">"; }

and grid:

var grid_metas = new ext.grid.gridpanel({              store       : store_grid_metas,             id          : 'grid_metas',             striperows  : true,             height      :  500,             width       : '100%',             autoscroll  : true,             frame       : true,             border      : true,             columnlines : true,             stateful    : true,             clickstoedit: 1,             items: [{                                  xtype: 'button',                                 itemid: 'btn_guardar_meta',                                 icon: '../../icons/add.png',                                 scale: 'small',                                 text: '<b>ingresar metas</b>',                                 handler: function(){                                        //modal_agregar_metas();                                  }                   }],              columns:[{                        xtype: 'gridcolumn',                       dataindex: 'meta',name: '',                       header: 'meta',                       sortable: true,                       grupable:true,                       width: 400,                                       },{                        xtype: 'gridcolumn',                       dataindex: '100%',name: '',                       header: '100%',                       sortable: true,                       grupable:true,                       align: 'center',                       width: 50,                       renderer : radiogrid                                  },{                        xtype: 'gridcolumn',                       dataindex: '75%',name: '',                       header: '75%',                       sortable: true,                       grupable:true,                       align: 'center',                       width: 50,                       renderer : radiogrid                   },{                      xtype: 'gridcolumn',                       dataindex: '50%',name: '',                       header: '50%',                       sortable: true,                       grupable:true,                       align: 'center',                       width: 50,                       renderer : radiogrid                   },{                        xtype: 'gridcolumn',                       dataindex: '25%',name: '',                       header: '25%',                       sortable: true,                       grupable:true,                       align: 'center',                       width: 50,                       renderer : radiogrid                   },{                        xtype: 'gridcolumn',                       dataindex: '0%',name: '',                       header: '0%',                       sortable: true,                       grupable:true,                       align: 'center',                       width: 50,                       renderer : radiogrid                   },{                        xtype: 'gridcolumn',                       dataindex: 'ponderación',name: '',                       header: 'ponderación',                       sortable: true,                       grupable:true,                       width: 150                   },{                        xtype: 'gridcolumn',                       dataindex: 'nota final',name: '',                       header: 'nota final',                       sortable: true,                       grupable:true,                       width: 150                   }],   })

the code display this:

perhaps try listener on grid handles cellclick event. using parameters ext passes handler, can access store record set or values needed: 

function(grid, rowindex, columnindex, e) {     var record = grid.getstore().getat(rowindex);  // record     var fieldname = grid.getcolumnmodel().getdataindex(columnindex); // field name     var data = record.get(fieldname); }
