你可以加载一个.Net表格作为控件吗？

using System.Data;
using System.Data.SqlClient;

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="ID" DataSourceID="SqlDataSource1">
   <Columns>
        <asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False" ReadOnly="True" SortExpression="ID" />
        <asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" />
        <asp:BoundField DataField="Age" HeaderText="Age" SortExpression="Age" />
    </Columns>
</asp:GridView>

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:YourConnectionString %>" SelectCommand="SELECT * FROM [YourTable]" UpdateCommand="UPDATE [YourTable] SET [Name] = @Name, [Age] = @Age WHERE [ID] = @ID">
   <UpdateParameters>
        <asp:Parameter Name="Name" Type="String" />
        <asp:Parameter Name="Age" Type="Int32" />
        <asp:Parameter Name="ID" Type="Int32" />
    </UpdateParameters>
</asp:SqlDataSource>

        // Initialize your data source here
        // For example, you can use a DataTable to store your data
        DataTable dt = new DataTable();
        dt.Columns.Add("ID");
        dt.Columns.Add("Name");
        dt.Columns.Add("Age");

        // Add your data to the DataTable

        using (SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["YourConnectionString"].ConnectionString))
        {
            using (SqlCommand cmd = new SqlCommand("SELECT * FROM [YourTable]", conn))

                conn.Open();
                using (SqlDataReader reader = cmd.ExecuteReader())

                        dt.Rows.Add(dr);
                    }
                }
            }
        }

        // Bind the data to the GridView control
        GridView1.DataSource = dt;
        GridView1.DataBind();
    }
