Righto, i'll get that uploaded to our repo now.
I'm still on a learning curve with GXT, so this should be fun.

Again, really good job mate. One of our users wants to buy you a beer

Just one more thing: If you used this with check boxes, would the gris cache those that are checked, ready for a "Save" action or would you recommend catching the event and updating the row on the server straight away?

[gslender]

Kango_V,

The CheckBoxSelectionModel plugin (checked etc) would need to be modified to support the remembering of checked state similar to the ActiveGridSelectionModel.

You could either keep a local index backed hash of checked rows or send them back to the server as you suggest (the server side would be slow though).

It wouldn't take me long (nor is it that hard) to create an ActiveCheckBoxSelectionModel.

I'm available for a fee if you wish

[Kango_V]

Yeah, that's what I thought. We may have a use case for this when our app has gone live.
I'm building a Production Services system to track fims, expenses, agreements, jobs, events, contracts etc etc etc.

It's getting bigger by the day. Also I've got to implement expenses into peoplesoft, contacts into Salesforce and invoices into Mapics/XA COM so the checkboxes could be useful. They keep us busy

Hehe, I'm still trying to get my boss to pay for an ExtGWT license.

Out of interest, what OS/IDE do you use to develop this stuff?

Windows XP and Eclipse 3.4 - but any OS/IDE would have worked as nothing about the OS or IDE was helpful in doing this work.

[Kango_V]

Hehe, yep. I use Ubuntu and Eclipse 3.4 here. I'm just being the nosy bugger that I am LOL.

hi grant!

this is really a great work!
could this become part of gxt itself? would be great .

maybe i am using it wrong, but i tried with a datasource which has 0 or 1 entry. this made it end up in an endless loop inside updateRows...

       if (realStore.getCount() < realStorePageSize) {
            refresh();
            return;
        }

refresh is always called and reloads... storeDataChanged(StoreEvent<M> se) is called after reload is finished and calls updateRows.... which itself calls refresh....

am i doing something wrong or is it a bug with smaller datasets?
anyhow: thanks for your great work!

regards, kht

Thanks - I did this to see even if it was indeed possible to extend GXT Grid ...and it was ;-)

An official GXT Active/Live Grid is being targetted for after 2.0 - so it is unknown if this ActiveGrid will be taken up. There are better ways to do what I have done so I'm fairly sure it won't be, but its a start

Ahh, yes this is expected. I never did consider someone using an active grid with no rows.

This is a bug. In fact it probably doesn't work very well at all with a small number (or zero) rows.

Feel free to have a tinker with the code - it shouldn't be too hard to fix the bug and get it working with large and small rows.

Hi Grant,

Any updates on ActiveGrid?

Are you planning on completing this? Or, is the plan to wait for a post 2.0+ version in GXT?

Thanks for all your work and effort on this widget, it is really important, IMO.

[gslender]

I'll happily add patches or fixes - but as a live grid equiv will be added eventually, there is no real point in me spending massive amounts of hours on it.

Cheers,
Grant
