C# 编辑gridview后无法更新对数据库的更改。并没有抛出错误，但数据库中的表中的更改不会更新

网络配置

<add name="MyConnection" connectionString="Data Source=HABIBDEA-PC;Initial Catalog=kopma;Persist Security Info=True;User ID=sa;Password=ilovedea1" />
<add name="kopmaConnectionString" connectionString="Data Source=HABIBDEA-PC;Initial Catalog=kopma;User ID=sa;Password=ilovedea1"
  providerName="System.Data.SqlClient" />
<add name="kopmaConnectionString2" connectionString="Data Source=HABIBDEA-PC;Initial Catalog=kopma;Persist Security Info=True;User ID=sa;Password=ilovedea1"
  providerName="System.Data.SqlClient" />

    </asp:GridView>
    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:kopmaConnectionString %>" SelectCommand="SELECT [NIM], [STATUSANGGOTA] FROM [datauser] WHERE ([STATUSANGGOTA] = @STATUSANGGOTA)" 
    UpdateCommand="UPDATE datauser SET [STATUSANGGOTA]=@STATUSANGGOTA WHERE [NIM]=@NIM">
        <SelectParameters>
            <asp:Parameter DefaultValue="AKTIF" Name="STATUSANGGOTA" Type="String" />
        </SelectParameters>
    </asp:SqlDataSource>

2.这是我的连接字符串

public partial class UserAktif : System.Web.UI.Page
{
    SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["MyConnection"].ToString());
    String s = "AKTIF";
    protected void Page_Load(object sender, EventArgs e)
    {
        gvbind();
    }

    </asp:GridView>
    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:kopmaConnectionString %>" SelectCommand="SELECT [NIM], [STATUSANGGOTA] FROM [datauser] WHERE ([STATUSANGGOTA] = @STATUSANGGOTA)" 
    UpdateCommand="UPDATE datauser SET [STATUSANGGOTA]=@STATUSANGGOTA WHERE [NIM]=@NIM">
        <SelectParameters>
            <asp:Parameter DefaultValue="AKTIF" Name="STATUSANGGOTA" Type="String" />
        </SelectParameters>
    </asp:SqlDataSource>

我的aspx代码

编辑

更新


取消

你能帮我吗？

若我单击“更新”，并没有错误，但并没有对数据库和gridview、tolong bisa gaa、kerjaan KP inih-.-

进行任何更改。最后，我使用了默认的gridview更新命令

    </asp:GridView>
    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:kopmaConnectionString %>" SelectCommand="SELECT [NIM], [STATUSANGGOTA] FROM [datauser] WHERE ([STATUSANGGOTA] = @STATUSANGGOTA)" 
    UpdateCommand="UPDATE datauser SET [STATUSANGGOTA]=@STATUSANGGOTA WHERE [NIM]=@NIM">
        <SelectParameters>
            <asp:Parameter DefaultValue="AKTIF" Name="STATUSANGGOTA" Type="String" />
        </SelectParameters>
    </asp:SqlDataSource>

我用这个，做得很好^^

    </asp:GridView>
    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:kopmaConnectionString %>" SelectCommand="SELECT [NIM], [STATUSANGGOTA] FROM [datauser] WHERE ([STATUSANGGOTA] = @STATUSANGGOTA)" 
    UpdateCommand="UPDATE datauser SET [STATUSANGGOTA]=@STATUSANGGOTA WHERE [NIM]=@NIM">
        <SelectParameters>
            <asp:Parameter DefaultValue="AKTIF" Name="STATUSANGGOTA" Type="String" />
        </SelectParameters>
    </asp:SqlDataSource>

对我来说工作很好

你的连接字符串在哪里？？？i、 e coni看不到您的连接字符串，但您仍然说没有错误，因为它可以是pblm with query.。您在where条件下缺少字符串的单引号。

update datauser set STATUSANGGOTA='“+status.Text.ToString（）+”'where NIM='“+NIM.Text.ToString（）+”'“，con）

不更新数据库，但我更新了我的代码的详细信息，仍然没有在数据库中更改对不起，但是现在我使用nim=@nim，仍然没有在数据库中更改database@HabibWisnuP您能为这两个变量创建一个messagebox吗？？

    </asp:GridView>
    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:kopmaConnectionString %>" SelectCommand="SELECT [NIM], [STATUSANGGOTA] FROM [datauser] WHERE ([STATUSANGGOTA] = @STATUSANGGOTA)" 
    UpdateCommand="UPDATE datauser SET [STATUSANGGOTA]=@STATUSANGGOTA WHERE [NIM]=@NIM">
        <SelectParameters>
            <asp:Parameter DefaultValue="AKTIF" Name="STATUSANGGOTA" Type="String" />
        </SelectParameters>
    </asp:SqlDataSource>
