TValueListEditor.SetRowCount procedure
Sets the value in the RowCount property.
Declaration
procedure SetRowCount(AValue: Integer)Arguments
AValue | New value for the property. |
Description
SetRowCount is an overridden procedure used to set the value in
the
RowCount property.
AValue contains the new value
for the property.
AValue cannot contain a value smaller than the number of FixedRows
for the grid control. An EGridException exception is raised when
AValue is less than the number of FixedRows for the control.
SetRowCount uses the RowCount value inherited from the grid to
determine if any actions are required in the method. No actions are performed
in the method when the inherited RowCount contains the same value as AValue.
SetRowCount ensures that the Strings property contains the number
of entries needed for the new property value minus the FixedRows for the
grid. Lines are added to or deleted from Strings until the number of entries
matches the needed value.
Errors
Raises an EGridException exception with the message in rsFixedRowsTooBig when the number of FixedRows is larger than the new value for the property.
