Multicolumn ListBox Display

[jspaarg]

Is it possible to change the rows being displayed in a multicolumn listbox without using the scroll bars?

I have a 2D array with all the strings for the box and it is updating fine with the scroll bars.

I want to remove the scroll bars and programatically display sequential groups of rows based on a different command.

The application is that I have 11 units, each with 16 devices on them for a total of 176 entries in my array.

I want the user to select 1 of 11 units, and I will display the 16 devices on the listbox.

Essentially unit 1 displays devices 1-16, unit 2 displays 17-32, etc.

Any ideas are appreciated.

Hi jspaarg,

      This example uses the TopLeft cell, and NumRows listbox properties - is it on the right track?

Cheers.

That solves part of the problem and is a little more elegant than how I am trying to do it, but the list box value does not change to reflect a selection.

For instance, if I am in group (section, whatever) 4, then the range is 48-63.  There does not seem to be a way to set the value in the list box (thus the highlighted row).

It seems that the value can only be in the range of 0-15 when the vertical scroll bars are missing.

Is there a way to highlight value 54 when the range is 48-63 and have the control indicate that it is 54 and not 7?

Thanks

Hi jspaarg,

      Here's another try.  The highlighted row can be set via the numeric control, or by clicking on the listbox.

> but the list box value does not change to reflect a selection

when you click on a row, "Selected" is updated with the new list box value - it seems to be correct!(?)

> There does not seem to be a way to set the value in the list box (thus the highlighted row).

modifying Selected assigns a new list box value - and the correct row seems to get highlighted - no?

I fear I'm missing your point and that there's some wierd phenomena I'm not observing...

Thanks, that is pretty much what I am trying to do.

The only exception is not being able to change the selected row when the segment changes.

I cannot find a way to do that either.

Perhaps I will put some type of error handler in place in case the user performs an operation that requires a selected row and the row is not in the segment.

Thanks again
