Hi,

Thanks so much for developing this! I've implemented it for a row-selection column in an attempt to make my grid behave similarly to Excel. Screenshot below:

Looks good. I've updated the version due to a bug when dynamically adding and removing locked columns. The bug probably won't affect mattpainter's excel like grid.

Have anyone got this working on a TreeGrid?

[Firelight]

Requesting a support for AggregationRowConfig in locked grid.

I'll try to investigate this issue myself. :)

Here is an update of my lockable grid:
(http://www.sencha.com/forum/attachment.php?attachmentid=31419&d=1328577817)
33601 (update - link fixed)

It's assembled by bolting two grids together, but it's usable and can support aggregation, buffered views etc.

The usage.txt doco shows how to add it to a content panel. Please comment / make updates etc.

(Move here from the new thread I mistakely created)

hi jackal

can share your GridHelper.class?

Sorry - LockableGridManager was not meant to be included. Imagine it as a some thoughts on managing a lockable grid. Grid Helper basically refreshes a grid by throwing away the store and creating a new one to prevent a whole lot of events from firing - a bit drastic really - probably could suppress events somehow.

Is there version of locking/freezing grid columns for GXT 3 ?

Is there version of locking/freezing grid columns for GXT 3 ?

There isn't at the moment - we haven't upgraded to GXT3 yet (and also was hoping that Sencha would see fit to create a proper version better than my hack).

Is there any update on lockable columns Grid in gxt 3???

I'm still using GXT 2 so no update from me - if you are a paying user send an email to Sencha to request lockable columns get added to the library! Requesting it may help convince Sencha that it's a useful feature.

It wasn't too hard to get the basic two grids synchronised - there are just some quicks to workaround. Give it a go and post back here - I and others can probably help with any issues.
