How to copy paste in Datagridview control


This post discusses how to add a datagridview and a contextmenustrip with cut, copy and paste into the form.

Image 1

Populate the DataGridView and define the click events as follows:

private void dataGridView1_CellMouseClick(object sender, DataGridViewCellMouseEventArgs e)
    if (dataGridView1.SelectedCells.Count > 0)
        dataGridView1.ContextMenuStrip = contextMenuStrip1;

private void cutToolStripMenuItem_Click(object sender, EventArgs e)
    //Copy to clipboard

    //Clear selected cells
    foreach (DataGridViewCell dgvCell in dataGridView1.SelectedCells)
        dgvCell.Value = string.Empty;

private void copyToolStripMenuItem_Click(object sender, EventArgs e)

private void pasteToolStripMenuItem_Click(object sender, EventArgs e)
    //Perform paste Operation

Copy/Paste routines follow...

The clipboard values are saved in a Dictionary, so the user can validate or manipulate the values before assigning them into gridviewcell.

private void CopyToClipboard()
    //Copy to clipboard
    DataObject dataObj = dataGridView1.GetClipboardContent();
    if (dataObj != null)

private void PasteClipboardValue()
    //Show Error if no cell is selected
    if (dataGridView1.SelectedCells.Count == 0)
        MessageBox.Show("Please select a cell", "Paste", 
		MessageBoxButtons.OK, MessageBoxIcon.Warning);

    //Get the starting Cell
    DataGridViewCell startCell = GetStartCell(dataGridView1);
    //Get the clipboard value in a dictionary
    Dictionary<int, Dictionary<int, string>> cbValue = 

    int iRowIndex = startCell.RowIndex;
    foreach (int rowKey in cbValue.Keys)
        int iColIndex = startCell.ColumnIndex;
        foreach (int cellKey in cbValue[rowKey].Keys)
            //Check if the index is within the limit
            if (iColIndex <= dataGridView1.Columns.Count - 1
            && iRowIndex <= dataGridView1.Rows.Count - 1)
                DataGridViewCell cell = dataGridView1[iColIndex, iRowIndex];

                //Copy to selected cells if 'chkPasteToSelectedCells' is checked
                if ((chkPasteToSelectedCells.Checked && cell.Selected) ||
                    cell.Value = cbValue[rowKey][cellKey];

private DataGridViewCell GetStartCell(DataGridView dgView)
    //get the smallest row,column index
    if (dgView.SelectedCells.Count == 0)
        return null;

    int rowIndex = dgView.Rows.Count - 1;
    int colIndex = dgView.Columns.Count - 1;

    foreach (DataGridViewCell dgvCell in dgView.SelectedCells)
        if (dgvCell.RowIndex < rowIndex)
            rowIndex = dgvCell.RowIndex;
        if (dgvCell.ColumnIndex < colIndex)
            colIndex = dgvCell.ColumnIndex;

    return dgView[colIndex, rowIndex];

private Dictionary<int, Dictionary<int, string>> ClipBoardValues(string clipboardValue)
    Dictionary<int, Dictionary<int, string>>
    copyValues = new Dictionary<int, Dictionary<int, string>>();

    String[] lines = clipboardValue.Split('\n');

    for (int i = 0; i <= lines.Length - 1; i++)
        copyValues[i] = new Dictionary<int, string>();
        String[] lineContent = lines[i].Split('\t');

        //if an empty cell value copied, then set the dictionary with an empty string
        //else Set value to dictionary
        if (lineContent.Length == 0)
            copyValues[i][0] = string.Empty;
            for (int j = 0; j <= lineContent.Length - 1; j++)
                copyValues[i][j] = lineContent[j];
    return copyValues;
