Question

我想建立一个旅馆杂费支付系统。假设有五个男孩成群地吃着食物，他们得到了5美元的账单。

我想通过网格视图选择5个成员，我希望5美元平均分配并添加到boys帐户中。在我的代码中，我想在Cnic的帮助下选择男孩，然后在数量上添加TextBox值。

如何在gridview中选择多行并以金额添加文本框值？我想在Cnic的帮助下更新数量。谁能帮我，这是代码：

namespace Mess_system
{
    public partial class Payment : Form
    {
    SqlConnection con = new SqlConnection("Data Source=DESKTOP-TTGKCGB;Initial Catalog=hostelmesssystem;Integrated Security=True");
    public Payment()
    {
        InitializeComponent();
    }

    private void textBox1_TextChanged(object sender, EventArgs e)
    {

    }

    private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
    {

        dataGridView1.MultiSelect = true;

    }

    private void Payment_Load(object sender, EventArgs e)
    {
        // TODO: This line of code loads data into the 'hostelmesssystemDataSet5.Registration' table. You can move, or remove it, as needed.
        this.registrationTableAdapter.Fill(this.hostelmesssystemDataSet5.Registration);
        //AddHeaderCheckBox();
        //HeaderCheckBox.MouseClick += new `enter code here`MouseEventHandler(HeaderCheckBox_MouseClick);

    }
    //CheckBox HeaderCheckBox = null;
    //bool IsHeaderCheckBoxClicked = false;
    //private void AddHeaderCheckBox()
    //{
    //    HeaderCheckBox = new CheckBox();
    //    HeaderCheckBox.Size = new Size(15,15);
    //    //Add Checkbox in the grid view
    //    this.dataGridView1.Controls.Add(HeaderCheckBox);
    //}

    private void gridview()
    {
        SqlCommand cmd1 = new SqlCommand("Select * From Registration ", con);
        con.Open();
        cmd1.ExecuteNonQuery();
        con.Close();
    }
    private void button1_Click(object sender, EventArgs e)
    {
        label2.Text = dataGridView1.SelectedRows.Count.ToString();

        if ((!string.IsNullOrEmpty(textBox1.Text)) && (!string.IsNullOrEmpty(label2.Text)))
        {
            label3.Text = (Convert.ToInt32(textBox1.Text) / Convert.ToInt32(label2.Text)).ToString("0");
        }
        else
        {
            MessageBox.Show("Select row or enter value");

        }
        float amount =Convert.ToInt32(label3.Text);

        SqlCommand cmd2 = new SqlCommand("Update Registration set Amount=  [Amount] +'" + amount + "'  Where Cnic='"+cnicDataGridViewTextBoxColumn.Selected.ToString()+ "'", con);
        con.Open();
        cmd2.ExecuteNonQuery();
        con.Close();

        this.registrationTableAdapter.Fill(this.hostelmesssystemDataSet5.Registration);
    }

    //private void HeaderCheckBoxClick(CheckBox HCheckBox)
    //{
    //    IsHeaderCheckBoxClicked = true;
    //    foreach (DataGridViewRow Row in dataGridView1.Rows)
    //        ((DataGridViewCheckBoxCell)Row.Cells["chk"]).Value = HCheckBox.Checked;
    //    dataGridView1.RefreshEdit();
    //    IsHeaderCheckBoxClicked = false;
    ////}
    //private void HeaderCheckBox_MouseClick(object sender  ,MouseEventArgs e)
    //{
    //    HeaderCheckBoxClick((CheckBox)sender);
    //}
    private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
    {


    }
}

我想从gridview中选择多个男孩，并想在他的帐户中添加文本框值。如何选择多个用户并在给定记录中添加文本框值？
