These frequently asked questions are product specific, for the dtrt.NavBarWin. If you are looking for answers to programming questions that do not concern dtrt.NavBarWin, refer to your development product's documentation or to the MSDN website. If you want answers to more general questions, please go back to the previous page and select the FAQ link for general questions.
Q: Why can’t I see all 6 default buttons in my navigation bar as
shown in the help documentation?
A: Not all buttons must be enabled and visible on a form containing
the dtrt.NavBarWin control. The application may not need them. If this is not
the case, check the Visible property of the respective buttons. Alternately
open the dtrt.NavBarWin Editor and check the buttons in the right listbox.
Q: Why is the Next button visible but disabled?
A: You have gone through all the records in the data and are now
positioned at the last record. The text display, if visible, should display “xx
of xx” with xx indicating the number of records. If you want to cycle from the
last to the first record you have to set the CycleRecs property to true. This
in turn also enables the Next button.
Q: Can a user change the increment of the Next Increment and
Previous Increment buttons?
A: If the navigation bar context menu is enabled, yes, else no. If
yes, changes can be made in the Change settings submenu of the Settings menu
item. Click on the menu item and enter the desired increment number in the
popup dialog. Click OK and the new increment is available immediately.
Q: Why is the increment value not always the same?
A: This is because you work with the increment type “percent” which
computes a certain percentage (default is 10%) of the total record number to be
the increment. If you have different total numbers of records, you also get
different computed increment values. You can change the increment type in the
IncrementType property and the increment value in the IncrementBy property.
Q: How do I start the dtrt.NavBarWin designer?
A: Call the dtrt.NavBarWin designer either by right-clicking on the
dtrt.NavBarWin on a form, then selecting “Design NavBarWin” in the context menu
or by selecting the property grid and clicking on the button with the three
dots in the dtrt.NavBarWin's “NavBarButtons” property.
Q: The button text is not saved properly - only a question mark or
other symbols are visible?
A: You probably tried to save non-standard symbols. Save your
form's code page as a Unicode file:
select 'File' menu - select 'Save Form as...' submenu - click on the arrow on
the 'Save' button to activate the drop down list - select 'Save with Encoding'
- click 'Yes' on next popup window - select 'Unicode (UTF-8 with signature)'.
Q: I cannot disable the About menu item in the context menu?
A: You have a test/evaluation, beta or school license or an invalid
license. Said license types cannot disable the About menu item. Alternately the
license file is not in the binary directory; copy it to the 'bin' directory of
your project (typically '.../Project/bin/Debug' or '.../Project/bin/Release'
for C# or '.../Project/bin' for VB). If the problem persists, contact our
license department.
Q: The context-sensitive help does not work, neither does
Intellisense. What is wrong?
A: You must use the Visual Studio .NET Combined Help Collection as
preferred Help system. See 'Help on Help' in the dtrt.NavBarWin developers help
on how to activate this Help collection.
Q: I cannot find any help pages with Visual Studio .NET 'Help Index...' or 'Help Search...'
A: Check if you are using the Visual Studio .NET Combined Help Collection and set the 'Filtered by' combo box on the Help window to (no filter).
