Grid performance

Hi,

I want to use the grid to display real time updates, which I receive from an applet (very fast updates)... what's the best way of updating the Grid? Should I store the data in an Array and refresh Cell by Cell as the values change?

Also what is the best way to reference the cells... should I use the array index or should I assign and ID to each cell?

Please help... thanks

P.S. Great grid

I think the best is (as you say) to store the data in JS array and refresh cell by cell (or full row if there are many cells changed) using array indices for addressing. I guess you may go up to something like 100 updates per second.

Small example:

window.setInterval(function(){
        var 
row 1;
        var 
col 1;
        
myData[row][col] = (new Date()).valueOf();
        
obj.getRowTemplate(row).getItemTemplate(col).refresh();
    }, 
100);
