Left Property

Returns the distance between the left edge of an object and the left edge of the control. This property is read-only at run-time. This property is not available at design-time.

Syntax

Visual Basic

'Declaration
 
Public ReadOnly Property Left As Integer

C#

public int Left {get;}

Remarks

For the ColScrollRegion object, the value returned is expressed in terms of the coordinate system specified by the control's container.

Example

Following code loops through all the row scroll regions and column scroll regions and prints out the matrix of the scroll regions. A scroll region is formed by the intersection of a row scroll region and a column scroll region. So if there were 2 column scroll regions and 2 row scroll regions, there would be total of 4 scroll regions formed by their intersections.
