<h3>
    Data Map
</h3>
<p>
    Data maps provide a grid with automatic look up capabilities. For example, you may want to display a customer's name instead of his/her ID, or a color name instead of its RGB value.<br />
    Columns with an associated data map can be sorted by the mapped display value instead of the binding value.<br />
    Columns with an associated data map show drop-down buttons that can be used for quick editing. If you do not want to show the drop-down buttons, set the column's <b>ShowDropDown</b> property to false.

<h4>
    Multi-column Data Map

<p>
    The columns of <b>MultiRow</b> control have a <b>DropDownCssClass</b> property that enables styling the drop-downs used to edit values in data-mapped columns.

<p>
    To see the multi-column editor in action, click one of the drop-down buttons in the "Color" column,
    or select a cell in that column and press F4:
