SmartViewport Reference

Refresh Method

Forces a complete refresh of the viewport. This method is particularly useful when controls are added dynamically at run-time.

Syntax

object.Refresh

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

Remarks

When controls are dynamically added at run-time or when the dimension and/or position of a contained control is changed from code, method Refresh will force the viewport to re-calculate its virtual page bounds.

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
