XML

<asp:GridView ID="GrdSample"  CssClass="task-table"  runat="server" Width="485px"  AutoGenerateColumns="False"
                                        AllowPaging="True" PageSize="12">
                                        <Columns>
                                            <asp:BoundField DataField="ColName" HeaderText="Name"  />
                                            <asp:BoundField DataField="ColAge" HeaderText="Age"  />

                                            <asp:TemplateField HeaderText="Delete"   >

                                               <ItemTemplate  >

                                                   <asp:DropDownList ID="ddlSubject"    AutoPostBack="True" onselectedindexchanged="ddlSubject_SelectedIndexChanged"  Width = "100px" runat="server"> </asp:DropDownList>


                                               </ItemTemplate>

                                                <FooterStyle HorizontalAlign="Center" />

                                                <HeaderStyle HorizontalAlign="Center" VerticalAlign="Top" />

                                                <ItemStyle HorizontalAlign="Center" />

                                             </asp:TemplateField>

                                        </Columns>
                                    </asp:GridView>

C# code:

C#

DropDownList ddlSubject = (DropDownList)GrdSample.Rows[iCount-1].FindControl("ddlSubject");

and then you can get any value of dropdown list and display any where , you can take a label in itemtemplate column and display it .

hi friend,

use hidden controls like this

ASP.NET

<asp:Label ID="something" style="display:none" Text="" runat="server"></asp:Label>

then store your previous dropdownlist value in LblPrevious.
for examples:

C#

LblPrevious.Text="your Dropdownlist value";
