Is it possible to paste Excel / CSV data from clipboard to DataGridView in C#?

I use DataGridView control to manage a simple dictionary (several columns and a few hundred rows). DataGridView functionality is almost sufficient. I can add new rows, modify values and copy data from it to Excel. One thing I cannot do is to copy data from Excel to my control. Is it possible with some properties? Or is some code required to do this?

Also this MSDN link: how to PASTE (Ctrl+V, Shift+Ins) the data from clipboard to DataGridView

With code for .NET C#, VB and C++

(In the GetData method you probably want to specify Format.UnicodeText)

this has been edited from the codeprojet writeup. Slightly different ` 

private void PasteClipboard()
        {
            try
            {
                string s = Clipboard.GetText();
                string[] lines = s.Split('\n');
                int iFail = 0, iRow = dgData.CurrentCell.RowIndex;
                int iCol = dgData.CurrentCell.ColumnIndex;
                DataGridViewCell oCell;
                if (dgData.Rows.Count < lines.Length)
                    dgData.Rows.Add(lines.Length-1);
                foreach (string line in lines)
                {
                    if (iRow < dgData.RowCount && line.Length > 0)
                    {
                        string[] sCells = line.Split('\t');
                        for (int i = 0; i < sCells.GetLength(0); ++i)
                        {
                            if (iCol + i < this.dgData.ColumnCount)
                            {
                                oCell = dgData[iCol + i, iRow];
                                if (!oCell.ReadOnly)
                                {

                                                              oCell.ValueType);
                                      //  oCell.Style.BackColor = Color.Tomato;
                                    }

                                        " to read only column setting", iFail));

You can read the excel sheet to a dataset then bind the dataset to the grid. I think you should be able to make your amendments then write out to excel again when finished editing.

Yes you can!

Take a look at some of the code here and see if that helps.
