Hi,
The below code may be help for you i used xmllist collection as my data
provider for data grid
private function fnUpDownData(event:MouseEvent):void
{
if(dataGrid.selectedItem != null)
{
var j:int = dataGrid.selectedIndex;
var intGetID:int;
var arr:Array;
var intUpDownDataID:int;
intGetID =
cuePointXMLList.getItemIndex(dataGrid.dataProvider[dataGrid.selectedIndex]);
intUpDownDataID =
cuePointXMLList.getItemIndex(dataGrid.dataProvider[dataGrid.selectedIndex]);
if(event.target.name == "btnUp")
{
if(dataGrid.selectedIndex > 0)
{
j = j - 1;
arr = new Array(cuePointXMLList.getItemAt(j));
}
}
else if(event.target.name == "btnDown")
{
if(j < dataGrid.dataProvider.length-1)
{
j = j + 1;
arr = new Array(cuePointXMLList.getItemAt(j));
}
}
cuePointXMLList.setItemAt(
new XML('<CuePoint>' +'<Time> '+dataGrid.dataProvider[intGetID].Time+'
</Time> ' +
'<Type> '+dataGrid.dataProvider[intGetID].Type+' </Type> ' +
'<Name> '+dataGrid.dataProvider[intGetID].Name+' </Name>
'+'</CuePoint>'),j);
if(arr != null)
{
cuePointXMLList.setItemAt(new XML('<CuePoint>' +'<Time> '+arr[0].Time+'
</Time> ' +
'<Type> '+arr[0].Type+' </Type> ' +
'<Name> '+arr[0].Name+' </Name> '+'</CuePoint>'),intUpDownDataID);
}
dataGrid.dataProvider = cuePointXMLList;
/* for(var i:int=0;i<dataGrid.dataProvider.length;i++)
{
cuePointXMLList[i].slideid = i+1;
} */
dataGrid.selectedIndex = j;
}
else
{
Alert.show('Select the Data Grid.');
}
}
