Hi Bob,
The code you listed as a "work-around" for you is exactly the same thing I
was doing before. I also confirmed that we're running the same version.
I'm glad you found a way to solve your problem, but I'm concerned that
there is an issue that remains unsolved.
One thing I noticed is that the first column of the listview is always left
aligned. You indicated before that your first column was right aligned.
This conflicts with the sample I tried. I can align second and subsequent
columns to center or right, but the first column is always left aligned. I
tried adjusting the alignment of the first column at runtime also, but it
just ignores the alignment. So, I'm not clear on how you were aligning the
first column to the right. Do you have the code that was faulting before?
If so, what is different about it than what you have listed as code that
works for you?
Either way, I tried a few more scenarios and was not able to observe the
behavior.
Thanks,
Rick [MSFT]

| Hello Rick:
|
| thank you for your reply and sorry for my delay ...
|
| I tried to create a small piece of code that would show
| better what the problem was but couldnt do it.
|
| It is very hard to pinpoint where the problem is cuz
| several .NET classes have been derived from, such as:
|
| - XItem class derives from ListViewItem;
| - XList class derives from ListView;
| - XYList class derives from XList; (borth XList and XYList
| have two columns)
|
|
| Now, I was trying to change the CheckBoxes property of
| XYList at runtime and it the checkboxes would fail to
| show. The items can be added/removed at runtime. The label
| of the first column (where a checkbox were to show) would
| be right-aligned and one would have to double-click on the
| cell to have the checkbox show up.
|
| The workaround? I found the following to work:
|
| bool existing = listView.CheckBoxes;
| listView.CheckBoxes = true;
| listView.Items.Add(new XItem(cust-obj));
| listView.CheckBoxes = existing;
|
|
| Im using Visual Studio 7.1.3088, .NET Framework 1.1.4322
| on Windows 2000 professional with Service Pack 4.
|
| My View property is set to Details.
|
| Thanx,
|
