GridView Item Widths
For the GridView, the ItemStyle and HeaderStyle classes have a Width property that you can set in the GridView class. However, if you run your application, you may see that it ignores the width that you specify. At first, I thought it was a bug, but as I read about it on the internet, it appears there is a deeper issue. It seems that the issue is a limitation of the HTML table itself, and how widths seemingly are ignored unless a width is specified on the table itself. I applied a width to the GridView control, and this resolved my issue, though I'm not certain that's the only factor involved.
