Sizing a listview's columns

I want to display a listview and I want to have it adjust the columns so
that the column width is the larger of:

* The width required to display the column heading
* The width required to display the largest value entry in the column

In other words the column is sized such that you can display all data in the
column but if the data is less than the width of the column title then I
need it set to the width of the column title so it's readable.

You get three options in .NET:
1. Set a column header with to "-2". This will size it to the column header
width.
2. Set a column header width to "-1". This will size it to the maximum
amounf of data in the column.
3. Set a column header width to an absolute number.

My way to solve my problem is to:
1. Load the titles into the column headers
2. Set the column header widths to "-2".
3. Read the column header widths and save
4. Load the data into the listview
5. Set the column header widths to "-1".
6. If the column header width now is less than the save column header width
then set it to the saved value.

Now the problem is that *sometimes* this works, and sometimes it doesn't!

Sometimes when you set the column header width to "-2" then you can look at
the width and it will be set to the real value that it adjusted the column
width to, to make it display the header.

Other times when you reread the width it still says "-2".

Anyone know why this is happening?

Anyone know how I can fix it?

Or is there an alternative, better, way of doing this?

Thanks in advance
