添加dropdownmenu - 按钮到gridview

Question

我正在试图弄清楚如何在我的网格视图中添加一个按钮，当单击时，会形成一个下拉菜单，其中包含可点击的选项并将触发某种事件。

[以下相关图片可能有助于概念化按钮的位置]

问题是，在添加行时或以任何方式出现时都不会显示。

这是我的代码：

  <asp:GridView runat="server" ID="grdvwDepositTransaction"
                AutoGenerateColumns="false" DataKeyNames="Status"
                OnRowCommand="grdvwDepositTransaction_RowCommand" OnRowDataBound="grd_RowDataBound"
                CssClass="grid">

               <Columns>
                  <asp:TemplateField>
              <ItemTemplate>
                <ul id="actionMenuHomeScreenPanel" style="display: none; margin-top: -6px; text-align: left; " onmouseover="javascript: showMenu(); return false;" onmouseout="javascript: hideMenu(); return false;" class="ui-menu">
               <li><a href="#" onclick="window.close();">Cancel</a></li>
                <li>
                    <asp:LinkButton ID="LinkButton1" runat="server" OnClick="btnValidateTotals_Click" Text="Validate Transactions" width="100px"></asp:LinkButton>
                </li>
               </ul>
                      </ItemTemplate>
               </asp:TemplateField>                      
                  <asp:BoundField DataField="DepositEntry.cardNumber" HeaderText="Card Number" ItemStyle-CssClass="mediumColumn columnCenter" />
                  <asp:BoundField DataField="DepositEntry.accountNumber" HeaderText="Account Number" ItemStyle-CssClass="mediumColumn columnCenter" />
                  <asp:BoundField DataField="DepositEntry.taxID" HeaderText="Tax ID" ItemStyle-CssClass="mediumColumn columnCenter" />
                  <asp:BoundField DataField="DepositEntry.firstName" HeaderText="Customer Name" ItemStyle-CssClass="mediumColumn columnCenter" />
                  <asp:BoundField DataField="DepositEntry.transactionDateTime" HeaderText="Transaction Date/Time" ItemStyle-CssClass="mediumColumn columnCenter" />
                  <asp:BoundField DataField="DepositEntry.cashAmount" HeaderText="Cash Amount" ItemStyle-CssClass="mediumColumn columnCenter" />
                  <asp:BoundField DataField="DepositEntry.depositAmount" HeaderText="Envelope Deposit Amount" ItemStyle-CssClass="mediumColumn columnCenter" />
               </Columns>
                    <EmptyDataTemplate>
                        <span style="font-weight: bold; text-anchor:middle;">No Transactions have been entered</span>
                    </EmptyDataTemplate>                   
            </asp:GridView>

使用TemplateField。看看这个例子

        <asp:TemplateField HeaderText="Administração">
                        <EditItemTemplate>
                            <asp:DropDownList ID="ddlAdministracao" runat="server" SelectedValue='<%# Bind("Administracao") %>' Width="90px">
                            <asp:ListItem Value="True" Text="Ativo" />
                            <asp:ListItem Value="False" Text="Bloqueado" />
                            </asp:DropDownList>
                        </EditItemTemplate>
                        <ItemTemplate>
                             <asp:Image ID="imgAdministracao" runat="server" ImageUrl='<%# (Eval("Administracao").Equals(true) ? "Image/OK.png" : (Eval("Administracao").Equals(false) ? "Image/no.png" : "~/Image/blank.gif"))%>' />
                        </ItemTemplate>
                    </asp:TemplateField>
