Infragistics.Win.UltraWinGrid Namespace > UltraGridBase Class : Rows Property

Returns a collection of the topmost level of rows in the grid. This collection will either contain all the rows in Band 0 or the top level of GroupBy rows (if GroupBy rows are being used.) This property is read-only at run-time and is not available at design-time.

Syntax

Visual Basic (Declaration) 
Public ReadOnly Property Rows As RowsCollection
C# 
public RowsCollection Rows {get;}

Example

Rows property off the UltraGrid returns a RowsCollection. This RowsCollection contains the top level rows as its elements. They can be instances of UltraGridRow or UltraGridGroupByRow if you have group-by rows in band 0. Using this collection, you can traverse down the rows hierarchy. Following code loops throgh the top level rows and prints out the number of child records each row has.

Remarks

The Rows collection provides a easy way to navigate through row hierarchy of the grid, determine whether the grid contains data, and determine how rows are being displayed in GroupBy mode. When displaying data in a standard hierarchical view, the Rows collection contains an UltraGridRow object for every top-level (Band 0) row in the grid. The UltraGridRow objects in the collection expose a ChildBands property, which returns a collection of Rows collections representing the rows of the bands which are children of the current row.

The Rows colelction is also useful in GroupBy mode, when the top-level band or bands of the grid may consist of virtual "group by" rows. In this case, you use the Rows collection to obtain all the GroupBy rows that are being displayed, and the ChildBand properties of those rows provide a way to drill down to the actual data.
