Is there a way to set the numbers or rows before scrolling?

I would like to set the grid in such a way that it allows 4 rows before scrolling and if greater that 4 rows, it starts to scroll. This is due to the size of my frame in one of my web pages.

Can anyone help??

is there a answer to this.

I am trying to display the row count on top of my grid as the user scrolls
as well as keep the relative row selected.
eg. if rows 1-5 of 20 are displayed and the seleted row is 3 then after scroll the couter may show 4-9 of 20 and the selcted row should be 6.

I kind of have this working .
The counter is an AW.UI.Label
And I call the following method on grid.onScrollTopChanged

The problem is that when the top or btm row is selected the scrollbar tends to 'do a dance' on fast scrolling.

Any Ideas

function updategrid2Count(preTopRow,value) {
  	//reset updategridIns row count label 
        var topRow, btmRow , selectedRows, selectedRow, selectOffset, newRow, x;
  		if (myData2.length == null || myData2.length == 0) {

            grid2Count.setControlText("No Records");
            
  		} else {
  			topRow = Math.round((obj.getScrollTop()/18)+1);
  			btmRow = topRow + 4;
  			
  			if (topRow < 1 || topRow > myData2.length || btmRow < 1 || btmRow > myData2.length ){
  				return;
  			}
  		
  			if (btmRow > myData2.length) {
  				btmRow = myData2.length ;
  			}
  			grid2Count.setControlText(topRow + " - " + btmRow +" of " + (myData2.length));
  		}
  		topRow = topRow -1;
  		btmRow = btmRow -1;
  		selectedRows = obj.getSelectedRows();
  		
  		if (selectedRows.length>0 ){
  			selectedRow = parseInt(selectedRows[0]);
  			// must deal with sorted rows
  			a = new Array();
            a=obj.getRowIndices();

            var i;
            if (a == null || a =="" ){
                selectOffset = selectedRow-preTopRow;
                newRow = topRow+selectOffset;
                //alert("PRE:"+topRow+"TOP:"+topRow+"SEL:"+selectedRow+"NEW:"+newRow);
            } else {
                for (x = 0; x < a.length; x++) {
                  if (a[x] == selectedRow){
                     break;
                  }
                }
                selectOffset = x-(preTopRow); //alert(x);
                var nrIdx = topRow+selectOffset;
                if (nrIdx>a.length -1) {nrIdx = x; }
                if (nrIdx<0) {nrIdx = x;}
                newRow = a[nrIdx];		
            }
             obj.setSelectedRows([newRow]);
             obj.setCurrentRow(newRow) ;						
  		}		
}
