Question

我有一个gridview，我正在尝试选择行ID（UrunId）。这是我的aspx：

<asp:GridView ID="GridViewHdcvi" runat="server" DataSourceID="EntityDataSourceHdcvi" AutoGenerateColumns="False" DataKeyNames="UrunId">
                                        <Columns>
                                            <asp:TemplateField HeaderText="Sil">
                                                <ItemTemplate>
                                                    <asp:LinkButton ID="deleteProduct" runat="server" Text="Satırı Sil" CommandName="deleteProduct">
                                                    </asp:LinkButton>
                                                </ItemTemplate>
                                            </asp:TemplateField>

                                             <asp:TemplateField HeaderText="Sil" Visible="false">
                                                <ItemTemplate>
                                                   <%#Eval("UrunId") %>
                                                </ItemTemplate>
                                            </asp:TemplateField>

                                            <asp:TemplateField HeaderText="ÜRÜN VE DETAYLARI">
                                                <ItemStyle Width="400px" />
                                                <ItemTemplate>
                                                    <div style="color: red" class="text-center"><%#Eval("UrunAdi") %></div>
                                                    <%#Eval("UrunDetay") %>
                                                </ItemTemplate>
                                            </asp:TemplateField>
                                            <asp:ImageField HeaderText="ÜRÜN GÖRSELİ" DataImageUrlField="UrunResim"></asp:ImageField>
                                            <asp:TemplateField HeaderText="BİRİM FİYAT">
                                                <ItemTemplate>
                                                    <%#Eval("UrunFiyati") %>
                                                </ItemTemplate>
                                            </asp:TemplateField>
                                            <asp:TemplateField HeaderText="ADET">
                                                <ItemTemplate>
                                                    <asp:TextBox ID="txtAdet" runat="server" Width="40px"></asp:TextBox>
                                                </ItemTemplate>
                                            </asp:TemplateField>
                                        </Columns>
                                    </asp:GridView>

正如您所看到的，我不希望用户看到我的＆＃34; UrunId＆＃34;列，但当用户点击＆＃34; deleteProduct＆＃34;时，我需要在代码隐藏中获取该行的UrunId。谢谢你的时间。

.ASPX标记

pm<-proc.time()
vys<-((x1==37) | (x2==37) | (x3==37) | (x4==37) | (x5==37) | (x6==37) | (x7==37) | (x8==37) | (x9==37) | (x10==37))
proc.time() - pm
#  user  system elapsed 
#  0.05    0.13    0.93 

pm<-proc.time()
vys1 <-  dt[, Reduce('|', lapply(.SD, '==', 37)), .SDcols= x1:x10]
proc.time() - pm
#   user  system elapsed 
#  0.05    0.03    0.08

背后的代码

<asp:TemplateField HeaderText="Sil">
         <ItemTemplate>
           <asp:LinkButton ID="deleteProduct" runat="server" Text="Satırı Sil" CommandArgument='<%#Eval("UrunId")%>' CommandName="deleteProduct" OnClick="LinkButton_Click">
               </asp:LinkButton>
          </ItemTemplate>
</asp:TemplateField>

OR

  protected void LinkButton_Click(Object sender, EventArgs e) 
  {
      LinkButton btn=(LinkButton)sender;
      int Id= Convert.toInt32(btn.CommandArgument);
      //Your delete code here
  }

在gridview中获取选定行的不可见ID
