新行的数据添加到GridView控件asp.net C＃ [英] Add new row data to gridview asp.net c#

问题描述

我做了一个类与此code：

 公共类客户
{
    公众客户（）{}
    公众客户（客户卡斯特）
    {
        ID = cust.ID;
        NAME = cust.Name;
        FatherName = cust.FatherName;
        电子邮件= cust.Email;
    }
    公众诠释ID {搞定;组; }
    公共字符串名称{;组; }
    公共字符串FatherName {搞定;组; }
    公共字符串电子邮件{获得;组; }
}
 

和创造了这个函数来加载一些数据列表：

 公开名单＆LT;客户＆GT; Generate_Data（）
{
    清单＆LT;客户＆GT; lstCustomer =新的List＆LT;客户＆GT;（）;
    客户客户=新客户（）;    customer.ID = 1;
    customer.Name =约翰Cena
    customer.FatherName =约翰;
    customer.Email =[e-mail];
    lstCustomer.Add（新客户（客户））;    customer.ID = 2;
    customer.Name =Mokesh;
    customer.FatherName =Rajnikant;
    customer.Email =[e-mail];
    lstCustomer.Add（新客户（客户））;    customer.ID = 3;
    customer.Name =比拉尔·艾哈迈德;
    customer.FatherName =Kashif;
    customer.Email =[e-mail];
    lstCustomer.Add（新客户（客户））;    customer.ID = 4;
    customer.Name =钦尚书;
    customer.FatherName =尚祸;
    customer.Email =[e-mail];
    lstCustomer.Add（新客户（客户））;    返回lstCustomer;
}
 

返回此列表与电网结合。在code是：

 列表＆LT;客户＆GT; lstCustomer =新的List＆LT;客户＆GT;（）;
lstCustomer = Generate_Data（）;
GridView1.DataSource = lstCustomer;
GridView1.DataBind（）;
 

我的问题是：

1. 我加4文本框和一个按钮的名称aspx页： ID，名称，FatherName，电子邮件
   当我按一下按钮，我想补充文本框的新值gridview1一行。我想添加一行来动态GridView的。




2. 如果我定义一个空的GridView，我怎么能加我的文本框值gridview的行？不等于法问题1？

解决方案

ASPX：

 ＆LT; ASP：文本框ID =TextBox1的=服务器＆GT;＆LT; / ASP：文本框＆GT;＆LT; BR /＆GT;
＆LT; ASP：文本框ID =TextBox2中=服务器＆GT;＆LT; / ASP：文本框＆GT;＆LT; BR /＆GT;
＆LT; ASP：文本框ID =TextBox3=服务器＆GT;＆LT; / ASP：文本框＆GT;＆LT; BR /＆GT;
＆LT; ASP：文本框ID =TextBox4=服务器＆GT;＆LT; / ASP：文本框＆GT;＆LT; BR /＆GT;
＆LT; ASP：按钮的ID =Button1的=服务器的onclick =的button1_Click文本=按钮/＆GT;
＆LT; ASP：GridView控件ID =GridView1=服务器/＆GT;
 

背后code：

 公共类客户
{
    公众客户（）{}
    公众客户（客户卡斯特）
    {
        ID = cust.ID;
        NAME = cust.Name;
        FatherName = cust.FatherName;
        电子邮件= cust.Email;
    }
    公众诠释ID {搞定;组; }
    公共字符串名称{;组; }
    公共字符串FatherName {搞定;组; }
    公共字符串电子邮件{获得;组; }
}

    如果（会话[DT]！= NULL）
    {
      lstCustomer =（列表＆LT;客户＆GT;）会议[DT];
    }
    客户客户=新客户（）;
    customer.ID = int.Parse（TextBox1.Text）;
    customer.Name = TextBox2.Text;
    customer.FatherName = TextBox2.Text;
    customer.Email = TextBox2.Text;
    lstCustomer.Add（新客户（客户））;
    GridView1.DataSource = lstCustomer;
    GridView1.DataBind（）;
    会话[DT] = lstCustomer;
}

        customer.FatherName =约翰;
        customer.Email =[e-mail];
        lstCustomer.Add（新客户（客户））;        customer.ID = 2;
        customer.Name =Mokesh;
        customer.FatherName =Rajnikant;

        customer.FatherName =Kashif;

        customer.Name =钦尚书;
        customer.FatherName =尚祸;
        customer.Email =[e-mail];
        lstCustomer.Add（新客户（客户））;
        会话[DT] = lstCustomer;    }
}
 

I've made a class with this code :

public class Customer
{
    public Customer() { }
    public Customer(Customer cust)
    {
        ID = cust.ID;
        Name = cust.Name;
        FatherName = cust.FatherName;
        Email = cust.Email;
    }
    public int ID { get; set; }
    public string Name { get; set; }
    public string FatherName { get; set; }
    public string Email { get; set; }
}

and created this function to load list with some data:

public List<Customer> Generate_Data()
{
    List<Customer> lstCustomer = new List<Customer>();
    Customer customer = new Customer();

    customer.ID = 1;
    customer.Name = "John Cena";
    customer.FatherName = "John";
    customer.Email = "[e-mail]";
    lstCustomer.Add(new Customer(customer));

    customer.ID = 2;
    customer.Name = "Mokesh";
    customer.FatherName = "Rajnikant";
    customer.Email = "[e-mail]";
    lstCustomer.Add(new Customer(customer));

    customer.ID = 3;
    customer.Name = "Bilal Ahmad";
    customer.FatherName = "Kashif";
    customer.Email = "[e-mail]";
    lstCustomer.Add(new Customer(customer));

    customer.ID = 4;
    customer.Name = "Chin Shang";
    customer.FatherName = "Shang Woe";
    customer.Email = "[e-mail]";
    lstCustomer.Add(new Customer(customer));

    return lstCustomer;
}

returning this list to bind with the grid. The code is :

List<Customer> lstCustomer = new List<Customer>();
lstCustomer = Generate_Data();
GridView1.DataSource = lstCustomer;
GridView1.DataBind();

My questions are :

1. I added 4 textboxes and a button to an aspx page with the names: Id,Name,FatherName,Email When I click on the button, I want add the new values of the textboxes to gridview1 row. I want to add a row to the gridview dynamically.

2. If I define an empty gridview, how can I add my textbox values to gridview rows? Is not equal method with question1 ?

解决方案

ASPX:

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox><br />
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox><br />
<asp:TextBox ID="TextBox3" runat="server"></asp:TextBox><br />
<asp:TextBox ID="TextBox4" runat="server"></asp:TextBox><br />
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />
<asp:GridView ID="GridView1" runat="server"/>

Code behind:

public class Customer
{
    public Customer() { }
    public Customer(Customer cust)
    {
        ID = cust.ID;
        Name = cust.Name;
        FatherName = cust.FatherName;
        Email = cust.Email;
    }
    public int ID { get; set; }
    public string Name { get; set; }
    public string FatherName { get; set; }
    public string Email { get; set; }
}
protected void Button1_Click(object sender, EventArgs e)
{
    List<Customer> lstCustomer = new List<Customer>();
    if (Session["dt"] != null)
    {
      lstCustomer = (List<Customer>)Session["dt"];
    }
    Customer customer = new Customer();
    customer.ID = int.Parse(TextBox1.Text);
    customer.Name = TextBox2.Text;
    customer.FatherName = TextBox2.Text;
    customer.Email = TextBox2.Text;
    lstCustomer.Add(new Customer(customer));
    GridView1.DataSource = lstCustomer;
    GridView1.DataBind();
    Session["dt"] = lstCustomer;
}

Updated!

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        List<Customer> lstCustomer = new List<Customer>();
        Customer customer = new Customer();

        customer.ID = 1;
        customer.Name = "John Cena";
        customer.FatherName = "John";
        customer.Email = "[e-mail]";
        lstCustomer.Add(new Customer(customer));

        customer.ID = 2;
        customer.Name = "Mokesh";
        customer.FatherName = "Rajnikant";
        customer.Email = "[e-mail]";
        lstCustomer.Add(new Customer(customer));

        customer.ID = 3;
        customer.Name = "Bilal Ahmad";
        customer.FatherName = "Kashif";
        customer.Email = "[e-mail]";
        lstCustomer.Add(new Customer(customer));

        customer.ID = 4;
        customer.Name = "Chin Shang";
        customer.FatherName = "Shang Woe";
        customer.Email = "[e-mail]";
        lstCustomer.Add(new Customer(customer));
        Session["dt"] = lstCustomer;

    }
}
