Examples of DataGridTagModel

org.apache.beehive.netui.databinding.datagrid.api.rendering.DataGridTagModel

The DataGridTagModel is a JavaBean that is exposed by the NetUI data grid tag into the {@link javax.servlet.jsp.PageContext} in a JSP. This bean exposes state and serviceswhich can be data bound by an expression language in a JSP.
