How do I add a listener to a CheckColumn?

[dkgemini]

Hi there

I am using a CheckColumn (plugin) in an EditorGridPanel. It updates fine with the info from my database (i.e. it shows checked/unchecked depending on the values 1 or 0 in the database). The problem comes when I check or uncheck the checkbox - the change doesn't get updated in the database. Changes to the other fields work just fine, it is just the checkbox that I can't seem to make work.

I have a feeling I have to use a different listener than afteredit (checkchange probably), but I can't figure out how.

I hope someone can help me.

Here's a some of my code, hopefully someone can help me - I am very green when it comes to Ext JS.

var checkColumn = new Ext.grid.CheckColumn({
        header: 'State funded',
        dataIndex: 'is_state_funded',
        width: 100,
        });

var grid = new Ext.grid.EditorGridPanel({

 columns: [
                {header: "ID", dataIndex: 'id', id: 'id', width: 35},
                {header: "School Name", dataIndex: 'school_name', id: 'school_name', editor: school_name_edit, width: 220},
                {header: "School Type", dataIndex: 'school_type', renderer: school_type_name, editor: school_type_edit, width:100},
        checkColumn
            ],
            }),
            sm: new Ext.grid.RowSelectionModel({
                singleSelect: true
            }),
            listeners: {
                afteredit: function(e){
                    Ext.Ajax.request({
                        url: 'schools-update.php',
                        params: {
                            action: 'update',
                            id: e.record.id,
                            field: e.field,
                            value: e.value
                        },
                        success: function(resp,opt) {
                            e.record.commit();
                        },
                        failure: function(resp,opt) {
                            e.record.reject();
                        }
                    });
                }
            },

the listener onMouseDown is already added to the Ext.grid.CheckColumn class.check/uncheck is handled there.

Thanks for that. I am still not sure how to do that... I ended up solving the problem in a different way.
