Linking database query to datagrid?

Question

Hi,
I am trying to to do a query from database and display the
result to the datagrid. I've heard people is doing it but how does
it work? Any reference?

Answer 1

i use java servlets.. the most challenging thing to me when
starting down this route was figuring out how to dynamically
configure the grid based on the data. almost every example i came
across required you to know the columns before receiving the data.
to create your own columns, you do something like:
var columNames:Array = [ "id", "name", "address" ];
var gridCols:Array = [];
var totalWidth:int = myGrid.width;
for each( var n:String in columnNames )
var column = new DataGridColumn();
column.dataField = n;
column.width = totalWidth / columnNames.length;
// set other properties like width, headerText, itemRenderer
etc
gridCols.push( column );
// set the grid columns which forces the redraw
myGrid.columns = gridCols;
