Data Map

This sample demonstrates how to use data map feature, which provides the MultiRow control with automatic look up capabilities.

Features

Data Map

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.

Columns with an associated data map can be sorted by the mapped display value instead of the binding value.

Columns with an associated data map, in this sample, 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 ShowDropDown property to false.

Multi-column Data Map

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

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:
