ValueLists Property

Returns a collection of ValueList objects. This property is read-only at run-time. This property is not available at design-time.
Syntax
'Declaration
 
Public ReadOnly Property ValueLists As Infragistics.Win.ValueListsCollection
public Infragistics.Win.ValueListsCollection ValueLists {get;}
Remarks

The ValueLists property is used to access the collection of ValueList objects associated with the UltraWinGrid. ValueList objects are used to provide the contents of the dropdown lists that are displayed in a cell when the column containing the cell has its Style property set to one of the dropdown list styles.

Each ValueList object in the collection can be accessed by using its Index or Key values. Using the Key value is preferable, because the order of an object within the collection (and therefore its Index value) may change as objects are added to and removed from the collection.

Example
Following code illustrates how to create a ValueList and assign it to a column. A ValueList maps data values to text. Depending on the value assigned to Style property of the column, cells in the column act like drop down lists or combo drop downs.
