如何从itemTemplate中的数据网格控制标签

            top: 4px" Width="300px" ForeColor="Black" BorderStyle="Solid" CellSpacing="2" OnSelectedIndexChanged="DataGrid3_editselected">
            <FooterStyle BackColor="#CCCCCC" />
            <SelectedItemStyle BackColor="#000099" ForeColor="White" Font-Bold="True" />
            <PagerStyle BackColor="#CCCCCC" ForeColor="Black" HorizontalAlign="Left" Mode="NumericPages" />
            <HeaderStyle BackColor="Black" Font-Bold="True" ForeColor="White" />
            <SelectedItemStyle BackColor="#000099" Font-Bold="True" ForeColor="White" />
            <Columns>
            <asp:ButtonColumn ButtonType="PushButton" Text="Edit this Product" CommandName="Select"></asp:ButtonColumn>
            <asp:TemplateColumn>
            <ItemTemplate>
            <table>
            <tr>
            <td>
            <asp:Label ID="ID" runat="server" Text=''<%# Eval("ID") %>'' Visible="false"  ></asp:Label>
            </td>
            <td></td><td></td><td></td><td></td><td></td><td></td><td></td><td></td>
            <td>
            <asp:Image ID="pic" runat="server" ImageUrl=''<%#"~/all/"+ Eval("Pic")%>'' Height="100" Width="100"></asp:Image>
            </td>
            <td>
            <asp:Label ID="cat" runat="server" Text=''<%# Eval("category") %>'' Visible="false" ></asp:Label>
            </td>
            <td>
            <asp:Label ID="model" runat="server" Text=''<%# Eval("carmodel") %>'' Visible="false" ></asp:Label>
            </td>
            <td>
            <asp:Label ID="year" runat="server" Text=''<%# Eval("year") %>'' ></asp:Label>
            </td>
            <td>
            <asp:Label ID="price" runat="server" Text=''<%# Eval("price") %>'' Visible="false" ></asp:Label>
            </td>
            <td>
            <asp:Label ID="stock" runat="server" Text=''<%# Eval("stock") %>'' Visible="false" ></asp:Label>
            </td>
            </tr>
            </table>
            </ItemTemplate>
                    </asp:TemplateColumn>
            </Columns>
            <ItemStyle BackColor="White" />
        </asp:DataGrid>

答案应该是这样的:(在c#后面的代码中)

The Answer Should be Somthing Like This:(in code behind c#)

Label mod = this.DataGrid3.SelectedItem.Cells[3].FindControl Label("model").Text;

推荐答案

protected void GridView1_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
   {
       Label model = (Label)GridView1.Rows[e.NewSelectedIndex].FindControl("model");
       // Do something

   }

希望对您有所帮助.

I hope this helps you well.

Label mod  = (Label)DataGrid3.SelectedRow.Cells[3].FindControl("model"); //just changed the index of cells based on your requirements
        if (mod != null)
        {
            string s = mod.Text;
        }
