推荐答案

这是我在form1中的代码:

使用系统；
使用System.Linq;
使用System.Collections.Generic;
使用System.ComponentModel;
使用System.Data;
使用System.Drawing;
使用System.Text;
使用System.Windows.Forms;
使用System.Data.SqlServerCe;

命名空间FirstSmartDeviceProject
{
公共局部类Form1:Form
{
公共Form1()
{
InitializeComponent();
}

/*重置按钮代码*/
私有无效btnreset_Click(对象发送者，EventArgs e)
{
txtuname.Text =";
txtpassword.Text =";
}

私有无效btnlogin_Click(对象发送者，EventArgs e)
{
AppDatabase1DataSet ds =新的AppDatabase1DataSet();
AppDatabase1DataSet.userDataTable dt =新的AppDatabase1DataSet.userDataTable();

this.userTableAdapter1.Fill(dt);

foreach(在dt.rows中的DataRow dr)
{
if(dr [1] .ToString()== txtuname.Text&& dr [2] .ToString()== txtpassword.Text)
{
txtpassword.Text =";
txtpassword.Text = dr [0] .ToString();

MessageBox.Show(登录有效！");
}
}
}

私有无效nextbtn_Click(对象发送者，EventArgs e)
{
表单名称=新的Form2(); Name.Show();

}
}
}

这是我在form2中的代码:

this is my code in form1:

using System;
using System.Linq;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Data.SqlServerCe;

namespace FirstSmartDeviceProject
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

/* Reset Button Code */
private void btnreset_Click(object sender, EventArgs e)
{
txtuname.Text = "";
txtpassword.Text = "";
}

private void btnlogin_Click(object sender, EventArgs e)
{
AppDatabase1DataSet ds = new AppDatabase1DataSet();
AppDatabase1DataSet.userDataTable dt = new AppDatabase1DataSet.userDataTable();

this.userTableAdapter1.Fill(dt);

foreach (DataRow dr in dt.Rows)
{
if (dr[1].ToString() == txtuname.Text && dr[2].ToString() == txtpassword.Text)
{
txtpassword.Text = "";
txtpassword.Text = dr[0].ToString();

MessageBox.Show("Login Valid!");
}
}
}

private void nextbtn_Click(object sender, EventArgs e)
{
Form Name = new Form2(); Name.Show();

}
}
}

and this is my code in form2:

using System;
using System.Linq;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace FirstSmartDeviceProject
{
    public partial class Form2 : Form
    {
        public Form2()
        {
            InitializeComponent();
        }

        private void Form2_Load(object sender, EventArgs e)
        {
            if (AppDatabase1DataSet2Util.DesignerUtil.IsRunTime())
            {
                // TODO: Delete this line of code to remove the default AutoFill for 'appDatabase1DataSet2.user'.
                this.userTableAdapter.Fill(this.appDatabase1DataSet2.user);
            }

        }

        private void backbtn_Click(object sender, EventArgs e)
        {
            Form Name = new Form1(); Name.Show();
        }
    }
}

我想在form1中将数据textboxt插入到form2中的datagridview中，并保存它.但是，如果我部署该代码，则form1中的文本框无法插入到datagridview form2中


....谁能帮助我....我是开发智能设备的初学者

i want to insert data textboxt in form1 to datagridview in form2, and save it. but if i deploy that code, textbox in form1 cannot insert in datagridview form2


....can any body help me....i am a beginner to development smartdevice
