[CLOSED] Grid Buffered Scrolling with Row Editing/Deletion/Addition

[asolvent]

Hi,

Is there any sample available which has grid buffered scrolling with new row, row editing and row deletion support?
Can CellEditing and RowEditing plugins be used with Buffered Scrolling?

Update: I can make it edit but no luck with new record insertion, any help would be much appreciated.

Cheers,
Avi

Hi @asolvent,

Are you using Biffered="true" for the Store? If so an insert operation is not supported for a buffered Store. As well as deletion.

I think that in this case the records should be inserted/deleted on server and the Store should be reloaded after that.

Thanks Danii, your clear answer is much appreciated.

Cheers,

Hi Danii,

Just curious, what might be the reason of leaving Add/Delete functionality from Buffered Grid, is that something which might come in any of the future releases?

Would you have any pointers if we intend to extend the functionality?

Thanks again for your help!

Cheers,

Here is some sort of answer.

I guess it is another reason why they didn't implement it - probably, it is quite hard to implement. Generally, I have no tips how to implement it. Probably, you should override/subclass those methods for adding and removing the records. But, probably, you will face the problems during implementation, the same ones that ExtJS team decided not to support it.

By the way, do you really need a Buffered Store? How many records are you going to load to the Store?

Well, there ain't lots of records as of now but the client has preference for continuous scrolling and we wanted uniformity in all the grids across the application.

Maybe, a BufferedRenderer plugin is good enough for you?

Please note that a Store has no Buffered="true" setting.
