Change "Eval" in your code to Bind

For example for a text box you will have:
<asp:TextBox ID="txtPOC" runat="server" text='<%#DataBinder.Bind(Container.DataItem, "POC") %>'
Font-Names="Arial" Font-Size="7pt" Width="32px"></asp:TextBox>

This sample code may help:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="BlackListID"
            DataSourceID="AccessDataSource1">
            <Columns>
                <asp:BoundField DataField="BlackListID" HeaderText="BlackListID" InsertVisible="False"
                    ReadOnly="True" SortExpression="BlackListID" />
                <asp:BoundField DataField="Tel_vc" HeaderText="Tel_vc" SortExpression="Tel_vc" />
                <asp:BoundField DataField="Comments_vc" HeaderText="Comments_vc" SortExpression="Comments_vc" />
                <asp:TemplateField HeaderText="mrt">
                    <ItemTemplate>
                        <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("Tel_vc") %>'></asp:TextBox>
                    </ItemTemplate>
                </asp:TemplateField>

will this automatically update the DataSet... ?  It does help in that on autopostback , the dropdown retains the value that it was changed to ... but when I submit the dataset to a table ..it shows the original value and not the one to which it was changed to..

    <asp:TemplateField>
                                          <ItemTemplate>
                                              <asp:DropDownList ID="ddnPOS24" runat="server" SelectedValue='<%#Bind("POS24") %>' Font-Names="Arial" Font-Size="7pt"
                                                  Width="40px"  AutoPostBack="True">
                                                  <asp:ListItem Selected="True">Fac</asp:ListItem>
                                                  <asp:ListItem>NonFac</asp:ListItem>
                                              </asp:DropDownList>
                                          </ItemTemplate>
                                      </asp:TemplateField>




This is how I read the dataset:


 For i = 97 To ds.Tables(0).Rows.Count - 1
            varstrSQL = varstrSQL + " Insert into " & varSelectedFSTblName & "(Fsname,Eff_DT, DEFPOC,POS, AnesCF,AnesMethod,SelectionType,ModelType)"
            varstrSQL = varstrSQL + "values( '" & ds.Tables(0).Rows(i).Item(2) & "','" & ds.Tables(0).Rows(i).Item(3) & "','" & ds.Tables(0).Rows(i).Item(4) & "','" & ds.Tables(0).Rows(i).Item(5) & "',"
            varstrSQL = varstrSQL + "'" & ds.Tables(0).Rows(i).Item(6) & "','" & ds.Tables(0).Rows(i).Item(7) & "','" & ds.Tables(0).Rows(i).Item(9) & "','" & ds.Tables(0).Rows(i).Item(8) & "')"
            cm.CommandText = varstrSQL
            cm.CommandType = CommandType.Text
            cm.ExecuteNonQuery()
            varstrSQL = ""
        Next

You should set the update query of your datasource to that your changes in dataset take effect in database.
