ColumnAttribute Component

The ColumnAttribute component is used as child of a GridPanel (or BridgePanel) component in order to select which columns should appear. By default GridPanel instances will show a selection of the attributes of the objects used in the data source. With the ColumnAttribute component the exact number (and which) of attributes can be selected.

XML Definition:

<xvw:columnAttribute 
   dataField='name' 
   ....

   label='Nome'
 >

</xvw:columnAttribute>
