MulitcolumnListBox Number of Columns increases without Data

[grep123]

Is there a way to avoid this ?

I initialize a 6 column 16 row multicolumnListBox by setting two columns, (the first and the last) as hidden by setting the width of the columns by setting the ActiveCell to 0 & -2 for the first column, and 6 & -2 for the last. This appears to work fine, however it would be nice that when you set the width of the column to 0 if it really "disappeared", but that's minor.

My real issue appears when I then attempt to set the height and fontsize of every cell, I do this by setting the ActiveCell to -2 & -2 and wire and unsigned int to the two property nodes, height, and fontsize. Now keep in mind the mulitcolumnListBox is defined as 6 columns by 16rows. After I initialize the table using the above code, the multicolumListBox blows up to 235 columns and 16row, with no data. So this leads me to believe that by setting the cell height, and default font size using the ActiveCell -2 & -2, it actually effects even those cells that are not visible or have data ? I should also mention that even with the Horizontal scroll bar visible it does not appear that there are more than 6 rows available, but when you read the property node, or look in the properties of the multicolumListBox they number of Columns increases to 235. Am I missing something ?

Hi Brad,

      I tried to duplicate this (under LabVIEW 7.1) but couldn't.

I suspect you're using 8.x as 7.1 doesn't seem to expose a "font size" cell-property.  No matter what version of LabVIEW you're using, attaching an example would be good.  

Cheers.

Hello Grep,

I'm having trouble recreating this issue on my end - if you could please post your VI, I could take a look at it.

Thanks!
