GetRow Method

Returns an UltraGridRow object for the first or last row in band 0.
Syntax
'Declaration
 
Public Function GetRow( _
   ByVal child As ChildRow _
) As UltraGridRow
public UltraGridRow GetRow( 
   ChildRow child
)

Parameters

child
Determines whether the first or last row in Band 0 is returned.

Return Value

The UltraGridRow object for the first or last row in Band 0
Remarks

The GetRow method is one of the mechanisms you can use to navigate through the hierarchical structure of the grid. You can use this method to return either the first or last raow in the topmost band, then walk through the rows in that band (using the HasNextSibling, HasPrevSibling and GetSibling methods. You can also step into the child band of any row using the HasChild and GetChild methods.

Example
Following code shows you how to traverse through all the rows in the UltraGrid. It finds out the number of regular rows (non-group-by rows) and number of group-by rows and shows the counts.
