It is very slow, 15 seconds to modify 84 rows of the table on a regular desktop computer (4GB ram). If the table is smaller it is a lot faster to modify the same amount of rows, which leads me to believe that somehow the whole table is recalculated by the browser every time a row is updated. Is there a way to avoid this and have the recalculation of the table done only once all updates are finished? The function looks like this: function OnACalcComplete2(result, userContext, methodName) { var grid = document.getElementById('<%=GridView1.ClientID%>'); var arrResult = result.split("\r\n"); // Update grid var i = 0; var gridIndex = 0; var arrResultRow; var arrCell; var gridRow = grid.rows[0]; for (i = 0; i < arrResult.length; i++) { arrResultRow = arrResult[i].split("\t"); gridIndex = arrResultRow[0]; gridRow = grid.rows[gridIndex]; arrCell = arrResultRow[arrResultRow.length - 1].split(";"); gridRow.cells[gridRow.cells.length - 1].innerText = arrCell[0]; // This is the slow part } } Is there some possibility to do for instance "Deactivate html parser" before the update and "Activate after"?
