Can I use JavaScript in 'Edit in DataSheet' mode?

Question

I would like to use some JavaScript in 'Edit in DataSheet' mode to check a value and prompt a user to enter some text.

Is this possible?

Answer 1

I'm sorry but you can't. The DataSheet mode uses a "SEALED" ActiveX Control. You have no control over the markup of this control(use IE Dev Toolbar and check it out) in order to control client side behaviour.

Answer 2

In SP2013 you can run javascript on top of datasheet view.

function CodeToRun(){//code here}

ExecuteOrDelayUntilScriptLoaded(CodeToRun, "callout.js");
