asp.net - Asp.Net Datagrid 视图未在新插入时更新

Question

好吧，正如标题所解释的那样，这是我到目前为止使用的代码

public partial class data : System.Web.UI.Page
{
    System.Data.SqlClient.SqlConnection con3;
    System.Data.SqlClient.SqlDataAdapter da;
    DataSet ds1;
    DataTable dt;
    string cs = System.Configuration.ConfigurationManager.ConnectionStrings["connect"].ConnectionString;
    protected void Page_Load(object sender, EventArgs e)
    {
        con3 = new System.Data.SqlClient.SqlConnection();
        con3.ConnectionString="Data Source=localhost; initial catalog=test;user id=xx;password=xxxx;";
        con3.Open();
        ds1 = new DataSet();
        SqlCommand cmd3 = new SqlCommand();
        cmd3.CommandType = CommandType.StoredProcedure;
        cmd3.CommandText = "selectdata";
        cmd3.Connection = con3;
        da = new SqlDataAdapter (cmd3);
        da.Fill(ds1, "abc");
        con3.Close();
        dt = new DataTable();
        dt = ds1.Tables[0];
        GridView1.DataSource = dt;
        GridView1.DataBind();

存储过程是

Create PROCEDURE [dbo].[selectdata] 
AS
BEGIN
    select * from data
END

我搜索了堆栈溢出并在 Google 上进行了搜索，但没有发生任何事情。我尝试在数据绑定后关闭连接，定义新数据集并再次创建表等等，请帮助

Answer 1

插入后尝试重新加载页面。

Answer 2

上面的答案只是刷新页面，所以在我看来它应该是

1--> 定义一个函数并在此绑定数据，例如

private void bind_data()
    {
        ASPxGridLookup2.DataSource = dt_employee;
        ASPxGridLookup2.DataBind();
        ASPxGridLookup3.DataSource = dt_attendance;
        ASPxGridLookup3.DataBind();
        ASPxGridView1.DataSource = dt_attendance;
        ASPxGridView1.DataBind();
    }

2--> 每当您需要刷新数据网格时调用此函数，例如在插入后立即

obj2.insertion();
       bind_data();
