标签: c# asp.net telerik

我有这个表单,当我点击保存客户时添加记录 将添加到数据库中并在gridview上显示添加记录 gridview连接在数据库上。 (没有人 gridview的问题。)

这是我的问题..
单击按钮后,我无法在数据库中添加记录 我认为问题在于背后的代码。

任何人都可以帮我解决我的代码有什么问题吗?

{
    SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["conn"].ConnectionString);

    protected void btnSaveCustomer_Click(object sender, EventArgs e)
    {

        cmd.Connection = conn;
        cmd.CommandText = "Insert into v.NewCustomer(FirstName, MiddleName, LastName, Address, Birthday, Age, Gender, ContactNumber) values (@FirstName, @MiddleName, @LastName, @Address, @Birthday, @Age, @Gender, @ContactNumber)";
        cmd.Parameters.AddWithValue("@FirstName", txtFirstName.Text);

        cmd.CommandType = CommandType.Text;
        conn.Open();
        cmd.ExecuteNonQuery();

        //SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["conn"].ConnectionString);

要刷新RadGrid并查看新添加的行,请使用Rebind()

RadGrid1.Rebind();
