Fantastic, that worked! :) Now, two more questions:

1) how do I hide the Done/Cancel dialog?

2) how to submit the last change in the grid when the user press submit button. I have noticed that if for example you edit one row, then go to another row (at this moment the first edited row becomes italic) and edit a cell then press Submit button, the last change is not part of the transacctions.

Thank you so much guy, you saved my life!

I found the answer to the first question (hide done/cancel dialog) using ShowDoneCancelButtons:

.Features(pFeatures => pFeatures.Updating().EnableAddRow(false).EnableDeleteRow(false).EditMode(GridEditMode.Row).ShowDoneCancelButtons(false))

Still waiting for the second question ,)

Hello Luis,

I am glad to hear this. Thank you for sharing your findings with us, I think that all other community members will benefit a lot from them.

I was wrong, I found that autocommit actually doesn't clear the transactions log, but this does it:

var _response = new Dictionary<string, bool> { { "Success", true } };

Change it to false and that will not clear the transactions log.

var _response = new Dictionary<string, bool> { { "Success", false } };

Well, after some searching I found it, igGridUpdating makes the magic:

$("#saveChanges").bind({
    click: function (e) {
        $('#MyGrid').igGridUpdating('endEdit', true);
        $("#MyGrid").igGrid("saveChanges");
    }   
});

I realize that auto commiting is not what I really wanted because that clears the log of transactions in the client side and I want to manage batch updating. So, for now I have what I need. ;)

This person (http://ko.infragistics.com/community/forums/p/84236/421454.aspx#421454) was facing a similar problem. Now I remember that this happens with UltraWinGrid and UltraWinToolbars too, when the user press a tool in the toolbar the grid doesn't lose the focus because toolbars doesn't get focus, so the edited row is not commited. I had to force an update on the last edited row like this:

if( m_MyGrid.ActiveRow != null )
{
   m_MyGrid.ActiveRow.Update();
   m_MyGrid.PerformAction( UltraWinGrid.UltraGridAction.ExitEditMode );
}

I am guessing that something similar occurs with igGrid, that's why Done/Cancel dialog is useful, it performs a commit (well, that's what I understand). But in my case I don't want to use Done/Cancel, so the question is, how to force a commit over the last edited row on igGrid? Is there any other way?

Thank you for the video Kolev! I see that you use the Done/Cancel dialog, but I want to let users to change data then commit all changes without having to press on that dialog. My grid pretend to show a few of rows with checks, that is the only cell that user can edit, so it is not nice if users have to press Done on every row. I know the problem is with the last row as you can see in my video, it is never commited. That's why I want to force the commit with AutoCommit or with  $("#MyGrid").igGrid("commit"). How to do that? I mean, AutoCommit or "commit" is not working in my case.
