选中dataGridView中数据点击修改按钮,将选中的数据传到B窗体中的控件.
然后进行修改,完成后点击保存后,调用A窗体中dataGridView1绑定方法

现在问就是不知道如何在B窗体中调用A窗体里的数据绑定方法

A窗体中的代码
namespace WindowsFormsApplication1
{
    public partial class AForm : Form
    {
        public AForm()
        {
            InitializeComponent();
        }

        private void AForm_Load(object sender, EventArgs e)
        {
            LoingGridView();//调用GridView数据绑定方法
        }
        private void LoingGridView()//GridView数据绑定方法
        {
            SqlConnection conn = new SqlConnection("server=.;uid=sa;pwd=****;database=WHJLS_Wage");
            SqlDataAdapter sda = new SqlDataAdapter("select * from WHJLS_Login", conn);
            DataTable dt = new DataTable();
            sda.Fill(dt);
            dataGridView1.DataSource = dt;
        }

        private void tsbModify_Click(object sender, EventArgs e)//修改按钮
        {
            BForm b = new BForm(dataGridView1);
            b.ShowDialog();
        }
      
    }
}


B窗体中的代码
namespace WindowsFormsApplication1
{
    public partial class BForm : Form
    {
        public BForm(DataGridView dgv)
        {
            InitializeComponent();
            txtID.Text = dgv.SelectedCells[0].Value.ToString();
            txtUser.Text = dgv.SelectedCells[1].Value.ToString();
            txtPwd.Text = dgv.SelectedCells[2].Value.ToString();
        }
      
        private void BForm_Load(object sender, EventArgs e)
        {

        }

        private void tsbSave_Click(object sender, EventArgs e)//保存
        {
            //请问一下如何在这里调用A窗体中的
             LoingGridView()//GridView数据绑定方法
        }
    }
}

在线等待

兄弟们帮我顶起来啊,程序开发到这里卡住了.

有两种方式，
1、写一个类，类有LoingGridView()方法；A、B窗口声明该类，调用该类的LoingGridView()方法。
2、将上面A窗口的改成public static void LoingGridView()静态方法

B窗口
        private void tsbSave_Click(object sender, EventArgs e)
        {
           AForm.LoingGridView()
        }

收到,我先试试看

一改成静态方法以后就报dataGridView1为非静太字段或是什么错误的

一般情况下 ，不这么做。应该把B中的值传到A中，在A中操作。


A窗体中的代码
namespace WindowsFormsApplication1
{
    public partial class AForm : Form
    {
        public AForm()
        {
            InitializeComponent();
        }

        private void AForm_Load(object sender, EventArgs e)
        {
            LoingGridView();//调用GridView数据绑定方法
        }
        private void LoingGridView()//GridView数据绑定方法
        {
            SqlConnection conn = new SqlConnection("server=.;uid=sa;pwd=****;database=WHJLS_Wage");
            SqlDataAdapter sda = new SqlDataAdapter("select * from WHJLS_Login", conn);
            DataTable dt = new DataTable();
            sda.Fill(dt);
            dataGridView1.DataSource = dt;
        }

        private void tsbModify_Click(object sender, EventArgs e)//修改按钮
        {
            BForm b = new BForm(dataGridView1);
            if(b.ShowDialog()==DialogResult.OK）
            ｛
                 //这里可以读取到你填写的值，然后你想怎么处理就怎么处理,比如：
                  string id=b.ID;
                  string user=b.User;
                  string pwd=b.pwd;
                 LoingGridView();//GridView数据绑定方法
            ｝
        }
      
    }
}


B窗体中的代码
namespace WindowsFormsApplication1
{
    public partial class BForm : Form
    {
        public BForm(DataGridView dgv)
        {
            InitializeComponent();
            txtID.Text = dgv.SelectedCells[0].Value.ToString();
            txtUser.Text = dgv.SelectedCells[1].Value.ToString();
            txtPwd.Text = dgv.SelectedCells[2].Value.ToString();
        }
      
        private void BForm_Load(object sender, EventArgs e)
        {

        }

        //定义属性,取值
        Public string ID
        ｛
            get{return txtID.Text;}
         ｝
        Public string User
        ｛
            get{return txtUser.Text;}
         ｝
        Public string Pwd
        ｛
            get{return txtPwd.Text;}
         ｝
        private void tsbSave_Click(object sender, EventArgs e)//保存
        {
            this.DialogResult=DialogResult.OK
            
        }
    }
}

不好意思，没留意到这个，可以试下改成这样

A窗体中的代码
namespace WindowsFormsApplication1
{
    public partial class AForm : Form
    {
        public AForm()
        {
            InitializeComponent();
        }

        private void AForm_Load(object sender, EventArgs e)
        {
            LoingGridView();//调用GridView数据绑定方法
        }
        public void LoingGridView()//GridView数据绑定方法
        {
            SqlConnection conn = new SqlConnection("server=.;uid=sa;pwd=****;database=WHJLS_Wage");
            SqlDataAdapter sda = new SqlDataAdapter("select * from WHJLS_Login", conn);
            DataTable dt = new DataTable();
            sda.Fill(dt);
            dataGridView1.DataSource = dt;
        }

        private void tsbModify_Click(object sender, EventArgs e)//修改按钮
        {
            BForm b = new BForm(dataGridView1);
            b.Owner = this;   
            b.ShowDialog();
        }
      
    }
}


B窗体中的代码
namespace WindowsFormsApplication1
{
    public partial class BForm : Form
    {
        public BForm(DataGridView dgv)
        {
            InitializeComponent();
            txtID.Text = dgv.SelectedCells[0].Value.ToString();
            txtUser.Text = dgv.SelectedCells[1].Value.ToString();
            txtPwd.Text = dgv.SelectedCells[2].Value.ToString();
        }
      
        private void BForm_Load(object sender, EventArgs e)
        {

        }

        private void tsbSave_Click(object sender, EventArgs e)//保存
        {
            //请问一下如何在这里调用A窗体中的
            this.Owner.LoingGridView()//GridView数据绑定方法  
        }
    }
}

6楼的兄弟回答是正确的谢谢,7楼我看到的代码是乱码呵呵,总之也谢谢你.多谢谢大家帮助
