SmartViewport
Reference

PageHeight

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

Syntax

object.PageHeight

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 PageHeight value corresponds to the distance between the top-most and bottom-most contained controls. 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.

Example:

'Add a CommandButton to SmartViewport1
'with properties [Left=135;Top=135;Height=495;Width=1455;Index=0]


'Current PageHeight returns 630 (=135+495)
Debug.Print "PageHeight = "; SmartViewport1.PageHeight

'Load a new instance of Command1
Load Command1(1)
Command1(1).Top = 2400
Command1(1).Visible =
True

'Refresh the viewport
SmartViewport1.Refresh

'Current PageHeight is now 2895 (=2400+495)
Debug
.Print "PageHeight = "; SmartViewport1.PageHeight
