PROJECT DESCRIPTION
After the user clicks the Add New Record button, you may want to preset some information for them in certain cells. If using validation or hint messages (empty messages/placeholders) in a template column does not suit your needs, you can use the batch edit manager client-side API and the OnBatchEditOpened event to set a value in the cell with your code:
function OnBatchEditOpened(sender, args) {
if (parseInt(args.get_row().getAttribute("id").split("__")[1]) < 0) {//this is the insert row - its index is below 0
args.get_tableView().get_dataItems();//enumarate data items so they get created and you can use their API
var dataItem = $find(args.get_row().getAttribute("id"));//get the current data item (row)
var batchEditingManager = sender.get_batchEditingManager();//get the batch editing manager
//avoid wiping existing user input if the user goes back to the cell
if (batchEditingManager.getCellValue(dataItem.get_cell("myTargetColumn")) == "") {
sender.remove_batchEditOpened(OnBatchEditOpened);//avoid recursion
//use the batch edit manager API ot change cell values
var desiredValue = 55;
batchEditingManager.changeCellValue(dataItem.get_cell("myTargetColumn"), desiredValue);//pre-load the desired value
setTimeout(function () {
sender.add_batchEditOpened(OnBatchEditOpened);//return the event handler after a bit so it can keep working
batchEditingManager.openCellForEdit(dataItem.get_cell("cellWhereTheUserShouldStart"));//open the next cell in case the cell we changed was the first - it would have lost focus
}, 100);
}
}
//note: if you use validation, review how this works as validation changes which cells can open for editing and where focus lies, so you may need to tweak this
}
