View Full Version : RowEditing & Locking capability

26 Jan 2012, 2:46 AM

I've tried to instanciate a grid panel with a RowEditor, and 2 locked columns, but it doesn't work. Error :

headerCt is undefined

Apparently, with locked columns the grid in fact contains 2 subgrids, and the main grid doesn't have a headerCt.

Is there any hope of being able to combine a RowEditor within a grid with locked columns ?

Thanks in advance !

I dont know if I have correctly understood what you are trying to achieve. If you mean that you simply dont want to allow users to edit these 2 columns, then just remove the editor from there 2 columns. that way, when the row editor is activated, you can change the other columns but these 2 are not editable.

That's not what I'm trying to do, sorry if I haven't been very clear.

What I want :
- A grid
- With the first two columns "locked" (like in Excel when horizontal scrolling doesn't affect these columns - you can see an example here : http://dev.sencha.com/deploy/ext-4.0.0/examples/grid/locking-grid.html)
- A RowEditor, allowing me to edit the grid's data, including the first two columns

Ok. I tried doing this with my grid and got the same error. However, when I added
columnLines: true to the grid config (like in the example), the grid did appear although there are some other errors now and the rows arent editable...

the other error

this.headerCt is undefined

does not appear in Ext JS 4.0.7!

I don't see why the columnLines option should change anything in this problem... I tried to add this option, but the grid comportment (and the error about the headerCt) is still exactly the same. Only difference is - obviously - that lines are now displayed between each column :)

I forgot to specify that I'm using 4.0.7.

Edit : our posts crossed, and I confirm that I get the following error using 4.0.7 (whatever columnLines value is specified) :

headerCt is undefined

which happens on line 83893 of ext-all-debug.js, inside the initEditor function of RowEditor :

initEditor: function() {
var me = this,
grid = me.grid,
view = me.view,
headerCt = grid.headerCt;

return Ext.create('Ext.grid.RowEditor', {
autoCancel: me.autoCancel,
errorSummary: me.errorSummary,
fields: headerCt.getGridColumns(),

hidden: true,

editingPlugin: me,
renderTo: view.el

I agree that columnLines shouldnt cause any difference. From what I understand, since there are 2 grids now (the locked columns form a separate grid), the roweditor fails to get the columns because there are 2 grids. This might be a bug. Although I cant say for sure coz I havent digged into the code to check it out. I am afraid I am out of ideas.

Yeah I didn't really hope that it would work natively, given the way the lock columns are implemented. I just wanted to be sure that it's just a non-feature and not a bug.

Thanks for you help !
