從datagridview中選擇一列的所有值到其他datagridview中的單元格

大家好，如果可能的話，我希望你能得到幫助：

在第一個表單中，當我單擊Télécharger PDF按鈕而不選擇行時，它會在第二個表單中將資料發送到另一個表單，它會自動選擇所有DataGridView行TextBoxes：DataGridView

• 問題是我想在第二個單元格中添加第一列的所有值，例如“Arduino scotch” DataGridView。
• 我認為這與我想將 Sum 添加到 form2 的一個單元格中的總數相同。

表格1：

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }
     private void button1_Click(object sender, EventArgs e)
    {
         Form2 f2 = new Form2();

            string firstcol = textBox3.Text;
            string secondcol = textBox1.Text;
            string thirdtcol = dataGridView1.CurrentRow.Cells[0].ToString();
            string fourcol = dataGridView1.CurrentRow.Cells[4].ToString();

   //thirdcole and fourcol are not working even for 1 row

            string[] rows = { firstcol, secondcol, thirdtcol, fourcol };

            f2.dataGridView1.Rows.Add(rows);

            f2.Show();

            this.Hide();
        
    }

表格2：

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

    private void A_commande_etat_Load(object sender, EventArgs e)
    {

    }
}

uj5u.com熱心網友回復：

Form2添加一個方法，該方法采用fromdataGridView1并Form1遍歷 deciered 列并創建所需的連接/求和值，然后將其添加為dataGridViewin的新行Form2。

表格1

public partial class Form1 : Form
    {
        Form2 f2; //Don't create a new f2 object each time button is pressed
        public Form1()
        {
            InitializeComponent();

            f2 = new Form2();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            f2.Show();
            //Send the datagridview of Form1 to Form 2, let Form2 do all the logic
            f2.loadColumns(this.dataGridView1); 
        }
    }

表格2

using System.Text;

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

        public  void loadColumns(DataGridView dataGridView)
        {
            StringBuilder buildArticleString = new StringBuilder();

            int articleColIndex = 0; //Your article col index in Form1
            int totalColIndex = 4; //Your total col index in Form1
            int totalSum = 0;
            
            foreach(DataGridViewRow currentRow in dataGridView.Rows)
            {
                if (currentRow.Cells[articleColIndex].Value == null || currentRow.Cells[totalColIndex].Value == null)
                    continue;

                //Retrive cell value at article column for current row, append to stringbuilder
                buildArticleString.Append(currentRow.Cells[articleColIndex].Value.ToString());
                buildArticleString.Append("   ");


                int currentTotalValue = 0;
                //Checks if value in cell can be converted to int, skips if not
                if (Int32.TryParse(currentRow.Cells[totalColIndex].Value.ToString(), out currentTotalValue))
                {
                    totalSum  = currentTotalValue;
                }
            }

            buildArticleString.Remove(buildArticleString.Length - 3, 3); //Remove trailing "   ";

            //Make sure this matches your columns in Form2
            string[] rowValues = new string[] {"", "", buildArticleString.ToString(), totalSum.ToString(), "", "" }; 
            dataGridView1.Rows.Add(rowValues); //Add new row to Form2
        }
    }
