dtrt.NavBarWin Help |
Overview |
Please be aware that some of the
features discussed in this documentation may not be available to you because
your application does not enable them (for example: you may not have a
context menu for the navigation bar). This help documentation is based on a
standard navigation bar with default features, texts and behavior. Turn to your
application’s help documentation to read about the implemented functions in
your application and how to use them.
The dtrt.NavBarWin is a navigation bar control that helps
you navigate through data (a dataset table or data view or a collection to be
precise) displayed on a form. You can navigate in one of four ways:
- By
clicking on any one of the buttons in the navigation bar; the buttons can
also be selected by using the tab and enter keys
- By entering a value in the text
display in the navigation bar - i.E. '+3' jumps forward 3 records; or
'-8' jumps back 8 records
- By
entering a record number to jump to in the text display in the navigation
bar
- By
selecting a menu item in the context menu of the navigation bar
Either way will jump to the selected record, so that you can
read or change the record that is now displayed in the window.
If you delete or add a record, the dtrt.NavBarWin takes
notice and you can see the changes in the text display's total number of
records.
A typically configured horizontal dtrt.NavBarWin looks like
this:
You can see 3 buttons to the left and to the right of the
text display (a textbox) which currently reads “1 of 24”. The buttons let you
navigate to different records. The textbox display shows you your position in
the data and you can also use it to enter a record number to jump directly to
the specified record, see Buttons or Textbox Display for details.
Instead of clicking on the buttons you can also use shortcut
keys which enable you to press a key or sequence of keys to perform navigation,
see Shortcut Keys for details.
The buttons have tool tips showing you their function and
shortcut key. The control has a context menu which you activate by pressing the
right mouse key when the cursor is over the control (not over the textbox
though), see Context Menu for details.
