我正在为雇主建立一个网站，目前使用NorthWInd数据库作为示例。我正在尝试将this（插入部分）添加到我的网站。只有问题在于，列表视图中显示的示例是否可以使用GridView执行相同的操作？
使用C＃，ASP.NET，HTML，Javascript，SQL
无论什么语言都是必要的。

然后是代码
protected void Page_Load(object sender, EventArgs e)
{
//check whether page is postback or not
//if page is not postback at that time we bind the gridview
if (!Page.IsPostBack)
{
//call the function BindGridView
BindGridView();
}
}
public void BindGridView()
{
//here write connection string
string strsql = DBConnection.sqlstr;
//create object for sqlconnection
SqlConnection sqlcon = new SqlConnection(strsql);
//here i use the query
//create the object of sqlcommand
SqlCommand sqlcmd = new SqlCommand("select * from [User]", sqlcon);
//create sqldataadapter object and give the sqlcommand as parameter
SqlDataAdapter adp = new SqlDataAdapter(sqlcmd);
//declare the dataset
DataSet ds = new DataSet();
//fill dataset using fill method of SqlDataAdapter
adp.Fill(ds);
//bind the GridView1
GridView1.DataSource = ds.Tables[0];
GridView1.DataBind();
}
在插入时单击
protected void lnkInsert_Click(object sender, EventArgs e)
{
string strsql = DBConnection.sqlstr;
//create object for sqlconnection
SqlConnection sqlcon = new SqlConnection(strsql);
//here i use the query
string strQuery = "Insert into [User] (UserName,Address1,EmailAddress) values (@UserName,@Address1,@EmailAddress)";
//create the object of sqlcommand
SqlCommand sqlcmd = new SqlCommand(strQuery, sqlcon);
//find the footer row for UserName And Assign the value
sqlcmd.Parameters.Add("@UserName", SqlDbType.VarChar, 50).Value = ((TextBox)GridView1.FooterRow.FindControl("txtfooterUserName")).Text;
sqlcmd.Parameters.Add("@Address1", SqlDbType.VarChar, 50).Value = ((TextBox)GridView1.FooterRow.FindControl("txtfooterAddress1")).Text;
sqlcmd.Parameters.Add("@EmailAddress", SqlDbType.VarChar, 50).Value = ((TextBox)GridView1.FooterRow.FindControl("txtfooterEmailAddress")).Text;
//open the sql connection
sqlcon.Open();
// Execute the Insert Command In to Database
sqlcmd.ExecuteNonQuery();
//close the sqlconnection
sqlcon.Close();
//if record successfully insert we display the message
lblMessage.Visible = true;
//bind grid view for latest record
BindGridView();
}
