Your explanation is not clear. Can you show a script only what you do with the datagrid.

//courseList_dg is the datagrid. i have inserted three arrays in various conditions.. when i insert one array to datagrid i clear the datagrid first and then only i insert the array.
//this is my code

var xmlLoader:URLLoader = new URLLoader();
var xmlData:XML = new XML();

xmlLoader.load(new URLRequest("DomainDetail.xml"));
xmlLoader.addEventListener(Event.COMPLETE, LoadXML);

/* Reading the Various Domain names*/
function LoadXML(e:Event):void
{
xmlData = new XML(e.target.data);
}

function getDomain(myevent:Event)
{
var lst:List = myevent.currentTarget as List;
selectedDomain=lst.selectedItem.data;
displayDomain1(selectedDomain);
domainStart_list.clearSelection();
}

function displayDomain1(selectedDomain)
{
//Adds the domName array to the domain_list
var displayDomainObject:displayDomain=new displayDomain();
domain_list.dataProvider = new DataProvider(displayDomainObject.displayDomainFn(x mlData,selectedDomain));
domain_list.visible=true;
domain_list.addEventListener(Event.CHANGE, getDomainID);
}

var selectedDomainID:String;
//Gets the selected Domain ID
function getDomainID(myevent:Event)
{
var lst:List = myevent.currentTarget as List;
selectedDomainID=lst.selectedItem.data;
selectedDID=lst.selectedItem.data;
domain_list.clearSelection();
getdomainID1(selectedDomainID);
}

function getdomainID1(selectedDomainID:String)
{
courseList_dg.removeAllColumns();
if (selectedDomainID=="allDomains")
{
var allDoaminObject:AllDomain=new AllDomain();
courseList_dg.dataProvider=new DataProvider(allDoaminObject.AllDomainFn(xmlData)) ;
courseList_dg.visible=true;
courseList_dg.getColumnAt(0).width = 80;
}

else if(selectedDomainID=="search")
{

courseList_dg.getColumnAt(2).width = 450;

}

else
{
