You can write a labelfunction in this way
private function
labelFunction(value:object,column:dataGridColumn):String{
//value would contain data for the entire row
//var 1 and var2 would be your properties on the arraycollection of
the datagrid
return value.var1 + ' -- ' + value.var2;
//instead of appending string...you can also do multiplication,other
math functions on the values and return the value as a string
}
Just assign the labelFunction name to the labelfunction property on
the datagird
