copy Textbox1 input string to datagridview1 &datagridview1 to textbox2

Dear @Uday Dodiya

Thanks for your reply sir.it work well and what i need.

Here i have small impliment need i.e if textbox input ends without timing then gridview result should be by default 1.

pls refer image.

please help the recify code.

Thanks in advance.

Dear @Uday Dodiya,

Please rectify as per the requirment and share the code.

Thanks

Dear @Uday Dodiya

Thanks for your reply sir.

in textbox1 if we start open bracket then previous line should be by default  input should be 1 in gridview every line it will checked where open bracket is started then previous line ends input shoud be by default with 1 in gridview..

also copy from gridview1 data to textbox same as textbox1 input like open and close bracket.

Hope you understand.please share the revised code.

Thanks

Dear @Jayraj Chhaya / @Uday Dodiya

please find the result output given below attachment.

hope you understand my logic.if use open and closing bracket with timing then gridview output should be 

wothout bracket and timing should be another column.and before start bracket previuous row should be timing should be 1 by default .like below

c0 c1 c2

10 A

10 B  1 (HERE BYDEFULT 1 BECAUSE BELOW START WITH OPEN BRACKET IN TEXTBOX1 INPUT.)

8 C

2 D  8

ALSO SAME GRIDVIEW DATA COPY TO TEXTBOX2 SAME OPEN AND CLOSE BRACKET WHERE TIMING IS USED SAME AS TEXTBOX1.

Hope you understand my logic.

Thankyou

Hi,
The following code is working as I make the same application using your data.
You have to define two textboxes and make them multiline and one datagridview.

Following is code.

namespace WinFormsApp4
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();

            AddDummyDataToTextBox1();

            DefineColumnsForDataGridView();
        }

        // Add dummy data to textBox1
        private void AddDummyDataToTextBox1()
        {
           
            textBox1.Text = "8-C" + Environment.NewLine +
                            "4-A" + Environment.NewLine +
                            "4-D" + Environment.NewLine +
                            "[12-A]" + Environment.NewLine +
                            "8-B|3" + Environment.NewLine +
                            "2-A" + Environment.NewLine +
                            "[4-C]" + Environment.NewLine +
                            "2-D|12";
        }

        // Define Column For Datagridview Otherwise Gives Error
        private void DefineColumnsForDataGridView()
        {
            if (dataGridView1.Columns.Count == 0)
            {
                dataGridView1.Columns.Add("Column1", "Column1"); 
                dataGridView1.Columns.Add("Column2", "Column2");
                dataGridView1.Columns.Add("Column3", "Column3");
            }
        }

        private void button1_Click(object sender, EventArgs e)
        {
            // Step 1: Copy textBox1 to dataGridView1
            CopyTextBoxToDataGridView();

            // Step 2: Copy dataGridView1 back to textBox2
            CopyDataGridViewToTextBox2();
        }

        private void CopyTextBoxToDataGridView()
        {
            // Clear previous rows in dataGridView1
            dataGridView1.Rows.Clear();

            // Split textBox1 content by new line to get rows
            string[] rows = textBox1.Text.Split(new[] { Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries);

            foreach (var row in rows)
            {
                // Split each row into parts based on hyphens (or other delimiters)
                string[] columns = row.Split(new[] { '-', '[', ']', '|' }, StringSplitOptions.RemoveEmptyEntries);

                if (columns.Length > 0)
                {
                    while (columns.Length < 3)
                    {
                        Array.Resize(ref columns, 3);
                    }
                    dataGridView1.Rows.Add(columns);
                }
            }
        }

        private void CopyDataGridViewToTextBox2()
        {
            // Clear textBox2 before adding new content
            textBox2.Clear();

            // Loop through the DataGridView rows
            foreach (DataGridViewRow row in dataGridView1.Rows)
            {
                if (!row.IsNewRow) // Skip the new row added by default
                {
                    List rowValues = new List();

                    // Loop through each cell in the row
                    foreach (DataGridViewCell cell in row.Cells)
                    {
                        if (cell.Value != null)
                        {
                            rowValues.Add(cell.Value.ToString());
                        }
                    }

                    string formattedRow = string.Join("-", rowValues);
                    textBox2.AppendText(formattedRow + Environment.NewLine); // Add formatted row to textBox2
                }
            }
        }
    }
}

Output 1 : Before Button Click


Output 2 : After Button Click

Follow the steps below:

1. Copy textBox1 input to dataGridView1:
   • The input in textBox1 will be split into rows and columns based on the format.
2. Copy dataGridView1 content to textBox2:
   • After filling dataGridView1, on another button click, the contents will be transferred to textBox2 in the same format as the original textBox1.

// Assuming you have a Button (button1), a DataGridView (dataGridView1), 
// and two TextBoxes (textBox1, textBox2) in your form.

private void button1_Click(object sender, EventArgs e)
{
    // Step 1: Copy input from textBox1 to dataGridView1
    string[] rows = textBox1.Text.Split(new[] { Environment.NewLine }, StringSplitOptions.None);

    // Clear any existing data in DataGridView
    dataGridView1.Rows.Clear();
    dataGridView1.Columns.Clear();

    // Add columns to DataGridView
    dataGridView1.Columns.Add("Column1", "Column1");
    dataGridView1.Columns.Add("Column2", "Column2");
    dataGridView1.Columns.Add("Column3", "Column3");

    // Populate DataGridView with data from textBox1
    foreach (string row in rows)
    {
        if (!string.IsNullOrWhiteSpace(row))
        {
            // Split each row into values
            var rowData = row.Split(new[] { '-' }, StringSplitOptions.None);

            // Fill the remaining cells with values or empty strings
            dataGridView1.Rows.Add(rowData[0], rowData[1], rowData.Length > 2 ? rowData[2] : string.Empty);
        }
    }

    // Step 2: Copy content from dataGridView1 to textBox2
    StringBuilder textBox2Content = new StringBuilder();

    foreach (DataGridViewRow dgvRow in dataGridView1.Rows)
    {
        if (!dgvRow.IsNewRow)
        {
            // Get values from each row of DataGridView
            string column1 = dgvRow.Cells[0].Value?.ToString() ?? "";
            string column2 = dgvRow.Cells[1].Value?.ToString() ?? "";
            string column3 = dgvRow.Cells[2].Value?.ToString() ?? "";

            // Append formatted data back to textBox2
            textBox2Content.AppendLine($"{column1}-{column2}{column3}");
        }
    }

    // Set textBox2 content
    textBox2.Text = textBox2Content.ToString().Trim();
}
