View Full Version : grid.panel CheckboxModel cellModel check box STAYED CHECKED???

11 Apr 2013, 3:19 PM
Hi Everyone,

I am trying to build a datagrid that allows a user to TAB cell by cell and make changes... IF a change is made to the cell, I want the checkbox on the left to STAY CHECKED... What's happening now is the person is going in the cell, making a change and the checkbox isn't staying checked...

Here's the code:

editor: 'textfield'
selType: 'cellmodel',
plugins: [
Ext.create('Ext.grid.plugin.CellEditing', {
clicksToEdit: 1
selModel: sm,
renderTo: Ext.getBody(),

How can I get the check box to stayed checked? Also, if anyone can point me to the code that tells the checkbox to stay check on editing a cell, that would help a ton!

CellEditing implicitly assumes it's working with a cellmodel selectionModel type. While you could override the CellEditing class to prevent the editor from exclusively selecting the cell/row of the cell being edited that would involve overriding a private, undocumented method - not an advisable path to take.

Instead you may want to use a CheckColumn (http://docs.sencha.com/ext-js/4-2/#!/api/Ext.grid.column.CheckColumn) or BooleanColumn (http://docs.sencha.com/ext-js/4-2/#!/api/Ext.grid.column.Boolean) and check them programmatically keying off of the CellEditing class's edit (http://docs.sencha.com/ext-js/4-2/#!/api/Ext.grid.plugin.CellEditing-event-edit) event.
