SmartViewport Reference

PageTop

Returns the top coordinate of the viewport virtual page. This property is not available at design time and is read-only at run-time.

Syntax

object.PageTop

The object placeholder represents an object expression that evaluates to a SmartViewport object.

Remarks

This property is only available at run-time. The viewport internally mantains a virtual page which size and position are based on the layout of its visible contained controls. The top-most control will determine the PageTop value. If you add controls dynamically at run-time you should use the method Refresh to force the viewport to re-calculate its vitual page bounds. The PageTop property is always less or equal than zero.

Example:

'Add a CommandButton to SmartViewport1
'with properties [Left=135;Top=135;Index=0]

'Current PageTop returns 0
Debug.Print "PageTop = "; SmartViewport1.PageTop

'Load a new instance of Command1
Load Command1(1)
Command1(1).Top = -1200
Command1(1).Visible = True

'Refresh the viewport
SmartViewport1.Refresh

'Current PageTop is now -1200
Debug.Print "PageTop = "; SmartViewport1.PageTop
