word wrap a gridview column where the gridview is generated from an sql statement...

As the gridview is generated dynamically from an sql statement in the code behind page item template is never generated and therefore I am unable to edit it.

Code relating to the gridview is below:
<asp:GridView ID="GridView1" runat="server" BackColor="White"
BorderColor="#999999" BorderStyle="Solid" BorderWidth="1px" CellPadding="3"
ForeColor="Black" GridLines="Vertical" >
<alternatingrowstyle backcolor="#CCCCCC">
<footerstyle backcolor="#CCCCCC">
<HeaderStyle BackColor="Black" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#999999" ForeColor="Black" HorizontalAlign="Center" />
<SelectedRowStyle BackColor="#000099" Font-Bold="True" ForeColor="White" />
<sortedascendingcellstyle backcolor="#F1F1F1">
<sortedascendingheaderstyle backcolor="#808080">
<sorteddescendingcellstyle backcolor="#CAC9C9">
<sorteddescendingheaderstyle backcolor="#383838">

code behind is:

protected void dropDownRole_SelectedIndexChanged(object sender, EventArgs e)
{
try
{
sql = "SELECT FORMAT(Change_Date,'DD/MM/YYYY') As Change_Date , FORMAT(Change_Time,'HH:MM:SS') As Change_Time, Ticket, Customer, Server_Name, Role, Task, Change, Comment, Engineer FROM change_control WHERE Role ='" + dropDownRole.SelectedValue + "'";
oleDbconn.Open();
oleDbcomm = new OleDbCommand(sql, oleDbconn);
DataTable dt = new DataTable();
OleDbDataAdapter da = new OleDbDataAdapter(oleDbcomm);
da.Fill(dt);
GridView1.DataSource = dt;
GridView1.DataBind();
}
catch (Exception ex)
{
ex.Message.ToString();
}
finally
{
oleDbconn.Close();
}
}
