var varState            = String(returnObj[varName]["state"]);
var varCity             = String(returnObj[varName]["city"]); 

 arrDP.push({        //arrDP is array defined
  //Column          Value
  Select          : plid, 
  State           : varState,

var dp:DataProvider              = new DataProvider(arrDP);
var select:DataGridColumn        = dg.addColumn("Select");
var state :DataGridColumn        = dg.addColumn("State");
var city  :DataGridColumn        = dg.addColumn("City");    
dg.dataProvider                  = dp; //dg IS DATAGRID NAME AND dp IS DATAPROVIDER
}

valu开发者_如何学运维e for chekboxes is : 1 & 0. where 1 mean TRUE(selected) and 0 mean FALSE(not selected). my question is how to show checkboxes to be SELECTED for value 1?? as checkbox need an event to be occur for state change. I am using the following cellrender class.

Thanks in advance.

1. Create the CheckBox instance.
2. Check if the plid is 1 or 0 and toggle the checkbox accordingly.

Like so:

//The checkbox instance variable name in this example is cb
cb.selected = plid == 1 ? true : false;

The selected getter/setter indicates if the CheckBox is to be displayed as checked or not.
