Extjs checkcolumn disable for some rows, based on value

Question

I have a grid, with checkcolumn. It\'s dataIndex is, for example, \'checked\'.

I want to disable or hide checkboxes for some rows, where another value, \'can_be_chec

Answer 1

Using extjs 5 it is easier to return defaultRenderer in renderer method for target checkboxes and '' for others.

renderer: function (value, metaData, record) {
    return (record.isLeaf()) ? '' : this.defaultRenderer(value, metaData);
}

Such won't render checkbox itself but all the events (i.e. checkchange, itemclick, etc) will be remained. If you don't want them either, you may disable them in beforesmth event, for example

onBeforeCheckRequestsChange: function(me, rowIndex, checked, eOpts) {
    var row = me.getView().getRow(rowIndex),
        record = me.getView().getRecord(row);
    return !record.isLeaf();
},
