How to save in the dropdown the value choosed?

I have a GridView and a column with a DropDownList instead of TextBox. The drop down has 2 values (1.No, 2.Yes).

The problem is, I can only choose the value “Yes”. The code behind works for good for yes and I also added for value No.

And another thing is if I choose a value (“Yes”, for example), how can I bring it to the top of the DropDownList, because it’s always showing the default value (the value “No”).

HTML

 <!--Add other attributes as you need to the grid view-->
 <!--NOTE: **OnRowDataBound="GridView_RowDataBound"** -->
 <asp:GridView ID="GridView1" runat="server" 
       OnRowDataBound="GridView1_RowDataBound">
 <Columns>

   <asp:TemplateField HeaderText="Dropdown Column">
       <ItemTemplate>
          <asp:DropDownList ID="ddlYesNo" runat="server">
              <asp:ListItem Value="1" Text="No"></asp:ListItem>
              <asp:ListItem Value="2" Text="Yes"></asp:ListItem>
          </asp:DropDownList>
       </ItemTemplate>
   </asp:TemplateField>
   <!-- OTHER COLUMNS -->
 </Columns>
 <!-- REST OF THE STUFF -->

CODE BEHIND

 protected void GridView1_RowDataBound(Object sender, GridViewRowEventArgs e)
 {
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        DropDownList ddl = (DropDownList)e.Row.FindControl("ddlYesNo");
        ddl.SelectedValue = 
          ((System.Data.DataRowView)e.Row.DataItem) ["dataColName"].ToString();

    }
 }
