SalNumber DataContextNext( SalNumber nWhat )
The DataContextNext moves the focus to the next row in the table.
| Name | Description | SalNumber nWhat | Standard method parameter. Possible values are Const.METHOD_Inquire, Const.METHOD_Execute, Const.METHOD_GetType |
|---|
When nWhat = Const.METHOD_Inquire, TRUE is returned if focus row is not the last row in the table, FALSE otherwise.
When nWhat = Const.METHOD_Execute, applications should ignore the return value of this method.
If the change of focus causes the table to scroll, the framework calls MethodStateChanged to update state of all ContextMethod method.
