Anatomy of the Grid in 1.0 Alpha1

Sorry about that. Grab it again.

Awesome! works :-)

Seem to have a display problem with a double button with all my buttons, (there is an inner button in all the buttons). Not anything thats going to stop development though.

Anyone have any suggestions/experiences with the new data marshalling/modified/dirty aspect of the grid?

[jack.slocum]

It's in there to define the interface. Look for auto marshalling of changes in a future release.

Just teasing us to show what's to come eh?

Can't wait!

Jack:

In response to why I need the index... or perhaps I'm overlooking something.

When deleting a Record:

deleteTest : function() {
	var deleteRow = sm.getSelected();
	ds.remove(deleteRow);				
	sm.selectPrevious();
	// TODO if deleteRow was 0 how do we know to selectFirstRow
},

How do I know to call selectFirstRow if the user had clicked the first row?

Can you do that by looking at the index of the deleteRow? (untested)

if (ds.indexOf(deleteRow)) == 0) {
  sm.selectFirstRow();
}

Thanks Tim!

Code:

var deleteRow = sm.getSelected();
var deleteRowIdx = ds.indexOf(deleteRow);
ds.remove(deleteRow);				
if (deleteRowIdx === 0)
	sm.selectFirstRow();
else
	sm.selectPrevious();

Readers should note that the index has to be looked up before you delete it. Otherwise you will get -1 as it's already been deleted.
