Create Right Click Menu on dataGridView for entire row

Question

I have a simple dataGridView filled with stuff, now I want to be able to right-click the left side to highlight the entire row so I can insert or delete entire row. I've been searching for this for a while, but most of the time it's for single cells, I'm looking for a context menu that is used on entire rows.

There is another question that is similar but ultimately not exactly what I'm trying to do.

Thank you in advance!!

I've tried several things, but nothing seems to really be exactly what i'm trying to accomplish and my code is just getting messier and messier. Really all I want to do is be able to insert a row into the dataGridView object while the program is running. You can delete rows just by highlighting the row and hitting "delete", but hitting "insert" does nothing. :( — Argv
We are not magicians with a crystal ball. We can't see your code. We can't see your application. We can't see what's wrong. You must to provide a working example. Otherwise, stackoverflow is not the site to ask this kind of questions. If you read the help, normally this kind of questions will be closed by offtopic / too broad / unclear what you're asking. Good luck. — Marcos Pérez Gude
I know, I've been using stack overflow since 2008. I don't ask many questions, typically I can figure stuff out, but this is pretty new. Perhaps I'll just buy a C# book. lol — Argv
Maybe you are in the wrong site of stackexchange. I don't know. Stackoverflow is to help specific questions with specific problems. All that doesn't fit with this, is offtopic or too broad. If you use S.O. by 8 years as you said, I don't know why you ask this question. Probably you never will obtain an answer — Marcos Pérez Gude

I found a pretty easy way to do what I wanted to do. It goes like this:

first of all, hook up a mouseDown event:

dataGridView1.MouseDown += new MouseEventHandler(this.dataGridView1_MouseClick);

then, create the routine co-responding to the mouseDown event..

 private void dataGridView1_MouseClick(Object sender, MouseEventArgs e)
    {
        if (e.Button == MouseButtons.Right)
        {
            ContextMenu cm = new ContextMenu();
            this.ContextMenu = cm;
            cm.MenuItems.Add(new MenuItem("&Cut", new System.EventHandler(this.cut_Click)));
            cm.MenuItems.Add(new MenuItem("&Copy", new System.EventHandler(this.copy2_Click)));
            cm.MenuItems.Add(new MenuItem("&Paste", new System.EventHandler(this.paste2_Click)));



            cm.Show(this, new Point(e.X, e.Y));
        }

    }

Then add your event routines, such as:

private void cut_Click(Object sender, EventArgs e)
    {
        if (this.dataGridView1.GetCellCount(DataGridViewElementStates.Selected) > 0)
        {
            try
            {
                Clipboard.SetDataObject(this.dataGridView1.GetClipboardContent());
            }
            catch (System.Runtime.InteropServices.ExternalException)
            {
                MessageBox.Show("Clipboard could not be accessed. Please try again.");
            }
        }

        if (this.dataGridView1.SelectedRows.Count > 0)
        {
            dataGridView1.Rows.RemoveAt(this.dataGridView1.SelectedRows[0].Index);
        }

    }

which will add the copied cells to the clip board. Then to paste them, something like:

private void paste2_Click(Object sender, EventArgs e)
    {
        char[] rowSplitter = { '\r', '\n' };
        char[] columnSplitter = { '\t' };

        // Get the text from clipboard
        IDataObject dataInClipboard = Clipboard.GetDataObject();
        string stringInClipboard = (string)dataInClipboard.GetData(DataFormats.Text);

        // Split it into lines
        string[] rowsInClipboard = stringInClipboard.Split(rowSplitter, StringSplitOptions.RemoveEmptyEntries);

        // Get the row and column of selected cell in grid
        int r = dataGridView1.SelectedCells[0].RowIndex;
        int c = dataGridView1.SelectedCells[0].ColumnIndex;

        // Add rows into grid to fit clipboard lines
        if (dataGridView1.Rows.Count < (r + rowsInClipboard.Length))
        {
            dataGridView1.Rows.Add(r + rowsInClipboard.Length - dataGridView1.Rows.Count);
        }

        // Loop through the lines, split them into cells and place the values in the corresponding cell.
        for (int iRow = 0; iRow < rowsInClipboard.Length; iRow++)
        {
            // Split row into cell values
            string[] valuesInRow = rowsInClipboard[iRow].Split(columnSplitter);

            // Cycle through cell values
            for (int iCol = 0; iCol < valuesInRow.Length; iCol++)
            {

                // Assign cell value, only if it within columns of the grid
                if (dataGridView1.ColumnCount - 1 >= c + iCol)
                {
                    DataGridViewCell cell = dataGridView1.Rows[r + iRow].Cells[c + iCol];

                    if (!cell.ReadOnly)
                    {
                        cell.Value = valuesInRow[iCol+1];
                    }
                }
            }
        }
    }

I use [col+1] because the first item in the list is always a blank (""). Hope this helps someone. It works for me! :D
