Radio button in grid extjs
I've a grid, in one of the column, i've used renderer which will return html radio like this,

renderer:function(val){
return Ext.String.format("&ltinput type='radio' name='rowSelector' value={0} /&gt",val);
}

Hence it'll allow any one of the radio button to be selected. 

I'm not sure, is there a possibility to make this radio button mandatory ( when no radio button is selected, showing error message, allowBlank:false ).

Is it possible to have anyother way of implementing this ?

Can we validate whether one of the radio is selected by using extjs controls ?
