The click event on my drop down does not fire. I do not see an alert and when I add a breakpoint in Firebug, it does not reach the breakpoint. It does reach the click and double click events if I breakpoint those.
Specifically, when I:
- Double click to edit a line
- Pick the Customer Drop Down and pick something else
- Move to another line
then the line
alert("I changed");
Does not run.
I wonder if it’s because when I move to another line, the value gets reverted (even though I have commented out the restoreRow method)
Am I using the right event to capture when my drop down value changes (without having to change focus).

Additionally it’s unclear why you use both
inlineNavand manual call ofeditRowinside ofondblClickRow? If you would select row and then click on the button from the navigator thedataUrlwill not be adjusted.The reason of the main problem which you describe is wrong usage of
dataEvents. In the documentation of editoptions you will find thedataEventsis the property ofeditoptionslikedataUrlfor example. Currently you placeddataEventson the wrong place incolModel.I would recommend you additionally to read the answer which describe how you can use
dataUrlwhich parameters depend on the current selected row. Additionally I would recommend you to verify that you setCache-Controlin the response ofdataUrl(see the answer). Alternatively you can use anothe option described here.
