Examples

The following code example shows how to define a ListColumn<TBusinessObject> object, add the object to a ListColumnCollection<TBusinessObject>, and use a delegate method to define the display value for business objects that are listed in the column:

ListColumnCollection<BusinessObject> columns = null;
columns = new ListColumnCollection<BusinessObject>();

ListColumn<BusinessObject> column = null;
column = columns.Add("NetworkName", GetListColumnString);
column.IsRequired = true;

private static string GetListColumnString(BusinessObject businessobj) 
{
    return businessObj.ComputerName + " " + businessObj.NetworkName; 
}
