Spread.NET and javascript

Question

I’m trying to add a hold shift-click functionality to select a range of cells (Exactly what spread does in winforms by default).
What I’m trying to do is recognize when the shift key is first hit while the spread component is onfocus and saving the cell coordinates in hidden inputs.

For some reason, I cannot get a value from ActiveCol or ActiveRow. They are returning undefined. I tried presetting an active cell with code, but it is still returning undefined.

I also check the value of ‘ss’ and it’s returning an element.

        function shiftCheckDown(event)
        {
            var ss = document.getElementById('<%=FpSpread1.ClientID %>');

            //ss.SetActiveCell(0,3);

            if (ss != null) {

                var col = ss.ActiveCol;
                var row = ss.ActiveRow;
  //var col = FpSpread1.ActiveCol;
  //var row = FpSpread1.ActiveRow;


                if (event.keyCode == 16) {

                        alert(row);

                        document.getElementById('RowCoord').value = row;
                        document.getElementById('ColCoord').value = col;
                }           
            }
        } 

I’m using an onkeydown to call the function.

<FarPoint:FpSpread onkeydown="shiftCheckDown(event)" ID="FpSpread1" runat="server" ActiveSheetViewIndex="0" . . .  

Please let me know if you need more information.

Answer 1

ActiveCol and ActiveRow only works in IE

For Firefox and other browsers, you need to use GetActiveRow and GetActiveCol

            var col = ss.ActiveCol;
            var row = ss.ActiveRow;

            if (col == undefined) {
                var col = ss.GetActiveCol;
                var row = ss.GetActiveRow;
            }

Answer 2

Actually it is like this:

col = ss.GetActiveCol();
row = ss.GetActiveRow();
