DataWindow controls
If the HSplit Scroll property is enabled, the user can split the DataWindow control into two panes with separate scroll bars. The user moves the split bar to divide the DataWindow control into two panes.
If this property is not enabled, the user cannot split the DataWindow control.
To allow splitting the control into two panes:
Select the HSplit Scrolling check box on the General page of the control’s Properties view.
The HSplitScroll property takes a boolean value. The following example allows splitting of a DataWindow control dw_1:
dw_1.HSplitScroll = TRUE
