Adding and removing locked columns

[nicora]

I've spent a good amount of time today trying to find an example of how to lock columns after the grid has rendered. I was able to unlock a column, but locking did not work. This is my grid set up:



var grid = new Ext.grid.Grid('reqGrid', {
ds: ds,
cm: cm,
selModel: new Ext.grid.RowSelectionModel({singleSelect:true}),
loadMask: true,
autoHeight: false,
autoWidth: false,
enableColLock:true,
enableCtxMenu: false,
enableRowHeightSync: true
});


if in the column model i set the first column locked and run this following code, it works



grid.getColumnModel().setLocked(0, 0);


but then if I fire the following code to lock it again, nothing happens



grid.getColumnModel().setLocked(0, 1);


What am I missing? Are there any examples of how to do this, I couldn't even find setLocked in the documentation, but I may have just missed it.

Thanks in advance for the help!

Care to share your solution? It would be helpful if anyone has the problem in future.

basically, I registerd a refresh method for the coulumnlockchange event and it started to work.



function setEvents(){
grid.getColumnModel().on("columnlockchange", refresh);
}
function refresh(){
grid.getView().refresh();
}

They were removed from Ext 2.0. See here (http://extjs.com/forum/showthread.php?t=12866).

Client requirement, if we lose column locking in the future I will have to put it back in anyway.

Just wanted to throw this out there, but why would Ext remove column locking? It's typically bad business to take features away, could I suggest leaving us the option to include it or not?

There's another thread discussing this (maybe the grid3 preview thread). Basically I think it came down to a question of performance. That being said, maybe Jack/Brian can comment on the possibility of the current functionality being maintained in a compatibility section.

Column locking is one of the main reasons we decided to consider Ext. Would it be possible to get this feature in 2.0?
