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

I also ran into this problem and to take it a step further I needed to have a tooltip show over the checkbox. Here's the solution I came up with that seems to be the least invasive on the existing checkcolumn widget...

renderer: function (value, metaData, record) {
    // Add a tooltip to the cell
    metaData.tdAttr = (record.get("someColumn") === "") ? 'data-qtip="A tip here"' : 'data-qtip="Alternate tip here"';

    if (record.get("someColumn") === "") {
        metaData.tdClass += " " + this.disabledCls;
    }

    // Using the built in defaultRenderer of the checkcolumn
    return this.defaultRenderer(value, metaData);
}
