Description

Sets or returns the number of virtual rows the sheet requests at a time.

Syntax

long CSpreadSheet::GetVirtualRows( );
void CSpreadSheet::SetVirtualRows(long value);

[form.]fpSpread.VirtualRows[ = value&]

Remarks

The default value for the VirtualRows property is 0.

The minimum number of virtual rows the sheet can request is one screen of data. The QueryData event occurs when more data is needed.

This setting is applied to the current sheet setting unless you first set the Sheet property to specify the sheet for which you are setting the property.

The VirtualRows property does not have an effect unless the VirtualMode property is set to True.

Use the VirtualMode property to turn virtual mode on or off.
