EditGrid and Checkbox

[mkn]

It is easy to add a checkbox to an Editgrid and showing data goes just fne. However, I have not been able to find out how to grab any edit events from the box. What I have done is this:

ccolumn = new CheckColumnConfig("isIt", "IsIt?",35);
// create a new checkbox
CheckBox cb = new CheckBox();
cb.setAutoValidate(true);
// set the column editor
ccolumn.setEditor(new CellEditor(cb ));
// add the column
configs.add(ccolumn);  
//.. etc
cm = new ColumnModel(configs);  
cp = new ContentPanel();  
//..
Listener CbListener = new Listener(){
        public void handleEvent(BaseEvent be) {
            Window.alert("foo from the grid");
        }        
};

When getting data for the grid I have done as follows:

grid.addListener(Events.ValidateEdit,CbListener);
grid.addPlugin(ccolumn);  
// add the grid to the contentpanel
cp.add(grid);

The "ValidateEdit" is just an example - I have tried BeforeEdit and AfterEdit as well. The event fires just fine with a TextField but not with the checkbox field.

What am I doing wrong here? Am I totally lost with the editors? Are there any special things to take into account when using other than TextField cell editors?

have you tried "Events.Change" since that event is fired when a checkbox state is changed.

Yes, actually after trying all imaginable events I finally understood that CellEditor cb editor actually does not even replace the icon displayed. For some reason unknown to me I cannot even set the CellEditor for the CheckBox column. A TextField editor in the previous cell works just fine.

And I simply cannot see any of the events fire. No idea why. This weird behaviour probably makes me revert part of the project back to Flex. I have not yet seen any working example of an EditGrid checkbox, the examples do not have one and nothing found in the mighty Internet.

I am very grateful if anybody who has done this before is willing to share the secret...

You need to override onMouseDown of CheckColumnConfig. CheckColumnConfig doent use a real cell editor.

Thanks, Sven, I did not spot that one in the documentation (if it is there). Now things look a bit better though I need to create an absraction layer on top of the EditGrid mess!

There is no mess in the EditorGrid. It is just that CheckColumnConfig isnt using any CellEditor.

Sorry, I what I meant was that I really need to create an special component that incapsulates EditorGrid and a few other components - just to save time and make the code more concise.

For me any framework is a mess before I have my own abstraction level ready - and it is looking better already
