I have a textbox in a template column. I can't get the value using the same technique as for a bound column. What is the syntax for retrieving this value both in client-side JavaScript and server-side C#?

I would like to sum the values for all the textboxes in the column in codebehind TextChanged and also sum them clientside with Javascript.


....
 <telerik:GridTemplateColumn HeaderText="Amount Approved" UniqueName="AmtApproved" HeaderStyle-Width="55px"
                            ItemStyle-Width="55px" HeaderStyle-HorizontalAlign="Right" ItemStyle-HorizontalAlign="Right">
                            <ItemTemplate>
                                <asp:TextBox ID="AmountApproved" runat="server" Width="55px" OnTextChanged="AmountApproved_TextChanged"
                                    AutoPostBack="true" CssClass="numericAlign"></asp:TextBox>
                            </ItemTemplate>
                        </telerik:GridTemplateColumn>
                        <telerik:GridClientSelectColumn UniqueName="ClientSelectColumn" HeaderStyle-HorizontalAlign="Right" ItemStyle-HorizontalAlign="Right">
                        </telerik:GridClientSelectColumn>
                    </Columns>
                </MasterTableView>
                <ClientSettings AllowKeyboardNavigation="true" EnableRowHoverStyle="true" EnablePostBackOnRowClick="true">
                    <ClientEvents OnRowSelected="handleTextBoxValue" OnRowDeselected="handleTextBoxValue" OnActiveRowChanged="sumAmtApproved" />
                    <Selecting AllowRowSelect="true" />
                </ClientSettings>
            </telerik:RadGrid>
