Question

I have a rich text box(richTextBox1) in my program as shown bellow. But when I right click on it, it doesn't pop up a “copy, cut, past” window. Can you please tell me how can I enable this “copy, cut, past” window in to my Rich Text Box? I am new to C#, please let me know step by step, if you know how to solve this

If you have more than one RichTextBox then you can use this extension method:

public static void AddContextMenu(this RichTextBox rtb) {     if (rtb.ContextMenuStrip == null)     {         ContextMenuStrip cms = new ContextMenuStrip()         {             ShowImageMargin = false         };          ToolStripMenuItem tsmiUndo = new ToolStripMenuItem("Undo");         tsmiUndo.Click += (sender, e) => rtb.Undo();         cms.Items.Add(tsmiUndo);          ToolStripMenuItem tsmiRedo = new ToolStripMenuItem("Redo");         tsmiRedo.Click += (sender, e) => rtb.Redo();         cms.Items.Add(tsmiRedo);          cms.Items.Add(new ToolStripSeparator());          ToolStripMenuItem tsmiCut = new ToolStripMenuItem("Cut");         tsmiCut.Click += (sender, e) => rtb.Cut();         cms.Items.Add(tsmiCut);          ToolStripMenuItem tsmiCopy = new ToolStripMenuItem("Copy");         tsmiCopy.Click += (sender, e) => rtb.Copy();         cms.Items.Add(tsmiCopy);          ToolStripMenuItem tsmiPaste = new ToolStripMenuItem("Paste");         tsmiPaste.Click += (sender, e) => rtb.Paste();         cms.Items.Add(tsmiPaste);          ToolStripMenuItem tsmiDelete = new ToolStripMenuItem("Delete");         tsmiDelete.Click += (sender, e) => rtb.SelectedText = "";         cms.Items.Add(tsmiDelete);          cms.Items.Add(new ToolStripSeparator());          ToolStripMenuItem tsmiSelectAll = new ToolStripMenuItem("Select All");         tsmiSelectAll.Click += (sender, e) => rtb.SelectAll();         cms.Items.Add(tsmiSelectAll);          cms.Opening += (sender, e) =>         {             tsmiUndo.Enabled = !rtb.ReadOnly && rtb.CanUndo;             tsmiRedo.Enabled = !rtb.ReadOnly && rtb.CanRedo;             tsmiCut.Enabled = !rtb.ReadOnly && rtb.SelectionLength > 0;             tsmiCopy.Enabled = rtb.SelectionLength > 0;             tsmiPaste.Enabled = !rtb.ReadOnly && Clipboard.ContainsText();             tsmiDelete.Enabled = !rtb.ReadOnly && rtb.SelectionLength > 0;             tsmiSelectAll.Enabled = rtb.TextLength > 0 && rtb.SelectionLength < rtb.TextLength;         };          rtb.ContextMenuStrip = cms;     } } 

And use it like this: richTextBox1.AddContextMenu();

Try with this code

UPDATED CODE:

        private void richTextBox1_MouseUp(object sender, MouseEventArgs e)         {             if (e.Button == System.Windows.Forms.MouseButtons.Right)             {   //click event                 //MessageBox.Show("you got it!");                 ContextMenu contextMenu = new System.Windows.Forms.ContextMenu();                 MenuItem menuItem = new MenuItem("Cut");                 menuItem.Click += new EventHandler(CutAction);                 contextMenu.MenuItems.Add(menuItem);                 menuItem = new MenuItem("Copy");                 menuItem.Click += new EventHandler(CopyAction);                 contextMenu.MenuItems.Add(menuItem);                 menuItem = new MenuItem("Paste");                 menuItem.Click += new EventHandler(PasteAction);                 contextMenu.MenuItems.Add(menuItem);                  richTextBox1.ContextMenu = contextMenu;             }         }         void CutAction(object sender, EventArgs e)         {             richTextBox1.Cut();         }          void CopyAction(object sender, EventArgs e)         {             Graphics objGraphics;             Clipboard.SetData(DataFormats.Rtf, richTextBox1.SelectedRtf);             Clipboard.Clear();         }          void PasteAction(object sender, EventArgs e)         {             if (Clipboard.ContainsText(TextDataFormat.Rtf))             {                 richTextBox1.SelectedRtf                     = Clipboard.GetData(DataFormats.Rtf).ToString();             }         }  

if you want to copy paste with another application like notepad (without styles ) please replace following methods

       void CopyAction(object sender, EventArgs e)         {             Clipboard.SetText(richTextBox1.SelectedText);         }          void PasteAction(object sender, EventArgs e)         {             if (Clipboard.ContainsText())             {                 richTextBox1.Text                     += Clipboard.GetText(TextDataFormat.Text).ToString();             }         }
