No Data message

Hi,
I've attached a particular scenario encountered below which results in a undefined message being displayed on screen.
Is there anyway you could draw a blank grid with a 'No data found' message???

Thanks a mil for your nhelp

.active-grid-column {border-right: 1px solid threedshadow;}

// create ActiveWidgets Grid javascript object
var obj = new Active.Controls.Grid;

// set number of rows/columns
obj.setRowProperty("count", 20);
obj.setColumnProperty("count", 5);

// provide cells and headers text
obj.setDataProperty("text", function(i, j){return myData[i][j]});
obj.setColumnProperty("text", function(i){return myColumns[i]});

// set headers width/height
obj.setRowHeaderWidth("28px");
obj.setColumnHeaderHeight("20px");

// allow multiple selection
obj.setSelectionProperty("multiple", true);

// define action handler
var message = function(){
window.status = "Grid selection:" +
" latest=" + this.getSelectionProperty("index") +
" full list=" + this.getSelectionProperty("values") +
" (press Ctrl- to select multiple rows)."
}

// assign action handler to grid
obj.setAction("selectionChanged", message);

// write grid html to the page
document.write(obj);

</script>

maybe the error occurs because you never specific any real data but you define an array with 20 rows. it will cause the undefined error.

If you set the row/count to 0 you should see "No data found' message automatically.
obj.setRowProperty("count", 0);
