Set Checkbox boxLabel dynamically

[nevf]

I want to change the Label for a Checkbox dynamically. I have tried:

Ext.get('cb_folders').update( 'New Label' );

which gives an "Unknown runtime error" in IE8 and does nothing in Firefox and Firebug reports no errors.

This seems like it should be simple to accomplish. I have searched the forums and tried everything I can think of without success.

The config is:

    var fp = new Ext.FormPanel({
        frame: true,
        bodyStyle: 'padding:5px 5px 0',
        height: 110,
        anchor: '100%',
        items: [
                { xtype: 'label',
                  text: 'Search in:'
                },
                {
                    xtype: 'checkboxgroup',
                    id: 'search-in',
                    hideLabel: true,
                    autoWidth: true,
                    columns : [66, 66],
                    items: [
                        { boxLabel: 'Folders', id: 'cb_folders',
                          handler: function( checkbox, checked ) { checkbox_handler( checkbox, checked ); }
                        },
                        { boxLabel: 'Articles', id: 'cb_articles', checked: true,
                          handler: function( checkbox, checked ) { checkbox_handler( checkbox, checked ); }
                        }
                    ]
                },
...

I've made no further progress with this, can anyone help.

Same problem here... I have not been able to do this.

Ext.form.CheckBox does not have a method to do this. You would need to change the value of the <label> that Ext creates when it makes a cbox and also use the setRawValue method to keep them in synch.

Wouldn't it be easier to have two cboxes and toggle their visibility?

Try:

checkbox.wrap.child('.x-form-cb-label').update('other boxLabel');

Hi Condor,

the doco says wrap "Creates and wraps this element with another element ".

Don't suppose you could explain that in English if you have a second?

Try:

checkbox.wrap.child('.x-form-cb-label').update('other boxLabel');

Condor, thanks so much that works beautifully. It would be great to see a SetLabel() function added to Checkbox though.
