Extjs checkColumn

Question

I see the example in ExtJS, but it seems the checkColumn doesn't update the XML. The API is also not so helpful. What I wanted to do is something like this. When the user clicks the checkbox in the grid it will send an AJAX request.

Answer 1

columns: [{
        xtype: 'checkcolumn',
        width: 30,
        sortable: false,
        id: 'check1',
        dataIndex: 'check11',
        editor: {
            xtype: 'checkbox',
            cls: 'x-grid-checkheader-editor'
        },
        listeners: {
            checkchange: function (column, recordIndex, checked) {
                alert(checked);
                alert("hi");
            }
        }
    }
]

worked for me :)

Answer 2

in extjs4 you can do this. there is the 'checkchange' event, so you can have something like this :

{
    header: 'State',
    dataIndex: 'STATE',
    xtype: 'checkcolumn',
    editor: {
        xtype: 'checkbox',
        cls: 'x-grid-checkheader-editor'
    },
    listeners: {
        checkchange: function(column, recordIndex, checked) {
            console.log(checked);
            //or send a request
        }
    }
}
