Question

为什么gridView页面没有插入或更新或刷新。我做错了什么？

protected void DetailsView1_ItemInserting(object sender, DetailsViewInsertEventArgs e)
{
    using (SqlConnection cn = new SqlConnection(Utilities.ConnectionString()))
    using (SqlCommand cmd = new SqlCommand("uspUpdateDisplayHours", cn))
    {
        cn.Open();
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.ExecuteNonQuery();
    }
    this.DetailsView1.DataBind();
}

Answer 1

您的DetailsView1是否映射到代码前端的DetailsView1_ItemInserting方法？

<asp:DetailsView ID="DetailsView1 " runat="server"
      DataSourceID="SqlDataSource"
      DataKeyNames="HoursId"
      OnItemInserted="DetailsView_ItemInserted"
      OnItemUpdated="DetailsView_ItemUpdated"
      OnItemInserting="DetailsView_ItemInserting"
      OnItemUpdating="DetailsView_ItemUpdating"
      >

另外，要小心。有类似的事件：OnItemInserted，OnItemInserting和OnItemUpdated，OnItemUpdating。我猜你真的想要OnItemInserted和OnItemUpdated。
