Dear friends,

I set two template columns like this:

<ig:TemplateDataField Header-Text="Area" Key="Area">
                            <ItemTemplate>
                                <asp:DropDownList ID="ddlArea" runat="server" CssClass="commonDropdownStyle" Width="60px"
                                    AutoPostBack="true" OnSelectedIndexChanged="ddlArea_SelectedIndexChanged">
                                </asp:DropDownList>
                                <asp:RequiredFieldValidator ID="RequiredFieldValidator" runat="server" InitialValue=""
                                    Display="Dynamic" ControlToValidate="ddlArea" ErrorMessage="*"></asp:RequiredFieldValidator>
                            </ItemTemplate>
                        </ig:TemplateDataField>
                        <ig:TemplateDataField Header-Text="LotNo" Key="LotNo">
                            <ItemTemplate>
                                <asp:DropDownList ID="ddlLotNo" runat="server" CssClass="commonDropdownStyle" Width="60px">
                                </asp:DropDownList>
                                <asp:RequiredFieldValidator ID="RequiredFieldValidator" runat="server" InitialValue=""
                                    Display="Dynamic" ControlToValidate="ddlLotNo" ErrorMessage="*"></asp:RequiredFieldValidator>
                            </ItemTemplate>
                        </ig:TemplateDataField>

I want to set the value of DropDownList ddlLotNo dynamicly in the event ddlArea_SelectedIndexChanged

The problem is how to get ddlLotNo in the event of ddlArea_SelectedIndexChanged

Please advise!!
