推薦:在ASP.NET程序中創建唯一序號
如果在程序中需要創建全局唯一的序號,那么必須對創建序號的過程進行同步處理,防止多個并發訪問時出現相同序號的情況。下面列出幾種方法供大家參考。利用數據庫的方法后面的例子都基于MS

看了下國外某巨牛的BLOG,大概是講asp.net 2.0中用GRIDVIEW插入新記錄的,方法比較特別,但效果一般,故將程序轉之,較為簡單,不做解釋等。

以下為引用的內容:

  {

    GridView1.ShowFooter = false;

  }
  void AddButton1_Click(object sender, EventArgs e)
  {

    GridView1.ShowFooter = true;

  }

  void Button1_Click(object sender, EventArgs e)

  {
    
    TextBox customerID = GridView1.FooterRow.FindControl("CustomerIDTextBox") as TextBox;

    TextBox companyName = GridView1.FooterRow.FindControl("CompanyNameTextBox") as TextBox;

    DropDownList ContactTitle = GridView1.FooterRow.FindControl("ContactTitleDropDownList") as DropDownList;

    SqlDataSource1.InsertParameters["CustomerID"].DefaultValue = customerID.Text;

    SqlDataSource1.InsertParameters["CompanyName"].DefaultValue = companyName.Text;

    SqlDataSource1.InsertParameters["ContactTitle"].DefaultValue = ContactTitle.SelectedValue;

    SqlDataSource1.Insert();

  }
