Clearing ppViewer

rbuser

I have a form to display subsets of information requested by the user in
a ppViewer.
The user can request different data (eg: a different department) right
on the form. How can I clear the viewer between requests so that a
previous response does not remain on the screen - especially when no
records are selected by the next request? I have the following
connection of components:

ppViewer -> ppReport -> ppDBPipeline -> TDataSource -> TClientDataSet ->

TDataSetProvider -> TIBQuery -> TIBTransaction -> TIBDatabase

For each request I repopulate the TClientDataset.CommandText.

I would like to clear the viewer before I process the next request. How
best to do it?

Hi Patrick,

Try calling Viewer.ScreenDevice.RenderFullBlankPage to clear the TppViewer
component.
