Hi all,

I have an application that uses a Tree View to create 16 columns. The first 8 columns are identical (same data, same header labels) to the second 8 columns.

To begin the app, the first 8 columns are visible, while the second 8 are invisible. With the first 8 columns, all headers are perfectly CENTERED, as I want.

When I make the first 8 invisible and the second 8 visible, the column headers all shift over by one or two character and are no longer centered.(!) Why?

If I go ahead and swap the visibility again, the first 8 columns headers are now also shifted by that one or two character amount.

Is this a bug? Or is there a simple way to keep column headers centered (justified) when switching their visibility?

My tree view setup is shown below.

Thanks in advance.
