OK, I assume that you use ASP.NET 2003 with C#.
You can manage the grid's controls at grid databound event.
see this sample,
I Fill dataset11 with Categories table from Northwind database.
I Bind dataset11 to datagrid1.

AT HTML........

<asp:DataGrid id=DataGrid1 style="Z-INDEX: 101; LEFT: 8px; POSITION: absolute; TOP: 8px" runat="server" Width="464px" DataSource="<%# dataSet11 %>" DataKeyField="CategoryID" DataMember="Categories" AutoGenerateColumns="False">
    <Columns>
        <asp:BoundColumn DataField="CategoryID" SortExpression="CategoryID" HeaderText="CategoryID"></asp:BoundColumn>
        <asp:BoundColumn DataField="CategoryName" SortExpression="CategoryName" HeaderText="CategoryName"></asp:BoundColumn>
        <asp:BoundColumn DataField="Description" SortExpression="Description" HeaderText="Description"></asp:BoundColumn>
        <asp:TemplateColumn>
            <ItemTemplate>
                <asp:Button id="Button1" runat="server" Text="Button"></asp:Button>
            </ItemTemplate>
        </asp:TemplateColumn>
    </Columns>
</asp:DataGrid>
 

AT CS...

private void Page_Load(object sender, System.EventArgs e)
{
    sqlDataAdapter1.Fill(dataSet11);
    DataGrid1.DataBind();
}
 

private void DataGrid1_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
    if ((e.Item.ItemType == ListItemType.Item) ||
        (e.Item.ItemType == ListItemType.AlternatingItem) ||
        (e.Item.ItemType == ListItemType.SelectedItem))
    {
        decimal ID= decimal.Parse (((DataRowView)e.Item.DataItem)["CategoryID"].ToString());
        if(ID<5)
            ((Button)e.Item.FindControl("Button1")).Enabled = false;
    }
}
 

Hope this help your requirement.

Sorry for my late reply, because of my weekend days.
try like this, may be it ok!

Button b;
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
     if (e.Row.RowType == DataControlRowType.DataRow)
     {
         decimal id = Convert.ToDecimal(e.Row.Cells[0].Text);
         if (id < 5)
         {
             b = new Button();
             b.Text = "New Button";
             e.Row.Cells[3].Controls.Add(b);
         }
     }
}
