LockingGridPanel - Grid with fixed and scrolling columns

[Condor]

Note:
Starting from Ext 3.1 this extension has become part of the standard Ext examples and this thread will no longer be updated.

This gridpanel/editorgridpanel descendant allows you to lock columns in your grid, so they will remain fixed when the grid is scrolled.

Features:
- Re-adds locking column support from Ext 1.x.
- Supports locking/unlocking from the column menu.

The code has undergone serveral changes and is not yet fully tested. Please report any bugs you find in this thread.

The original Ext 2.x extension can be found here.

update 6:
- Initial release for Ext 3.0.
- Fixed horizontal scroll of unlocked area when clicking on the locked area.
version 1.7:
- New version numbering scheme.
- Fixed forceFit:true (although I don't see why you would want to use it).
- Fixed stripeRows:true.
version 1.7.1:
- Cleaned up display (separator line now full height and fixed 1px offsets).

Stuff to remember:
- IE can corrupt the downloaded archive - Use a different browser.

Hello, many thanks!

Is there any special reason why this is not a standard in Ext JS?

Good to see this back in Ext 3.+, Condor.

You are terrific! Keep up the wonderful work!

Condor, this is the best thing since sliced bread.

Is there a way to get this to work with your GroupHeaderGrid plugin though? The two of them combined is exactly what I need. The first column would be locked and would not have a colspan for its header, but I would need the others to have them. Is this at all possible?

No, LockedGridPanel and the GroupHeaderGrid plugin currently can't work together.

I created a LockedGroupHeaderGrid plugin once, but I haven't for the Ext 3.0 release (and, unless someone pays me, I'm not planning on creating one - it's a lot of work).

Create grid with forceFit:true leads to cyclic dependency

This happens because method updateAllColumnWidths call this.layout method and this.layout method call this.fitColumns which again call updateAllColumnWidth.

Posted in the Ext 2.x thread:

I noticed the stripeRows property isn't working on the locking grid (even in the example file) for update6.

I tried using getRowClass to do it but to no avail. Any ideas on how to resolve this?

BTW: Thanks for the 3.0 version. It is a real life-saver.

I will look into this (and the fitColumns problem) when I have some time to spare...
