I cannot determine how to determine the width of a particular gridview column. I get this result:

As you can see, I get a substantial overflow. I would like to determine the maximum width and wrap the test for this 5th column.
I tried to do this programmatically:
GridView1.Columns[4].ItemStyle.Width = 300; GridView1.DataBind();
And also in asp.net:
<asp:BoundField DataField="Description" HeaderText="Description" SortExpression="Description" ItemStyle-Width="300px" />
or
<asp:BoundField DataField="Description" HeaderText="Description" SortExpression="Description" HeaderStyle-Width="300px">
None of these attempts have any effect.
