Simply set form  Accept Button  Property to button that you want to hit by Enter key  Or in load event write this acceptbutton   btnName

The simple option is just to set the forms s AcceptButton to the button you want pressed  usually  OK  etc        TextBox tb   new TextBox        Button btn   new Button   Dock   DockStyle Bottom        btn Click    delegate   Debug WriteLine  Submit      tb Text          Application Run new Form   AcceptButton   btn  Controls     tb  btn         If this isn t an option  you can look at the KeyDown event etc  but that is more work         TextBox tb   new TextBox        Button btn   new Button   Dock   DockStyle Bottom        btn Click    delegate   Debug WriteLine  Submit      tb Text          tb KeyDown     sender args    gt            if  args KeyCode    Keys Return                        btn PerformClick                         Application Run new Form   Controls     tb  btn

I came across this whilst looking for the same thing myself  and what I note is that none of the listed answers actually provide a solution when you don t want to click the  AcceptButton  on a Form when hitting enter    A simple use-case would be a text search box on a screen where pressing enter should  click  the  Search  button  not execute the Form s AcceptButton behaviour   This little snippet will do the trick   private void textBox KeyPress object sender  KeyPressEventArgs e        if  e KeyChar    13                if   textBox AcceptsReturn                        button1 PerformClick                        In my case  this code is part of a custom UserControl derived from TextBox  and the control has a  ClickThisButtonOnEnter  property  But the above is a more general solution

The usual way to do this is to set the Form s AcceptButton to the button you want  clicked    You can do this either in the VS designer or in code and the AcceptButton can be changed at any time   This may or may not be applicable to your situation  but I have used this in conjunction with GotFocus events for different TextBoxes on my form to enable different behavior based on where the user hit Enter   For example   void TextBox1 GotFocus object sender  EventArgs e        this AcceptButton   ProcessTextBox1     void TextBox2 GotFocus object sender  EventArgs e        this AcceptButton   ProcessTextBox2      One thing to be careful of when using this method is that you don t leave the AcceptButton set to ProcessTextBox1 when TextBox3 becomes focused   I would recommend using either the LostFocus event on the TextBoxes that set the AcceptButton  or create a GotFocus method that all of the controls that don t use a specific AcceptButton call

The TextBox wasn t receiving the enter key at all in my situation   The first thing I tried was changing the enter key into an input key  but I was still getting the system beep when enter was pressed   So  I subclassed and overrode the ProcessDialogKey   method and sent my own event that I could bind the click handler to   public class EnterTextBox   TextBox        Browsable true   EditorBrowsable      public event EventHandler EnterKeyPressed       protected override bool ProcessDialogKey Keys keyData                if  keyData    Keys Enter                        EnterKeyPressed  Invoke this  EventArgs Empty               return true                    return base ProcessDialogKey keyData

This is very much valid for WinForms  However  in WPF you need to do things differently  and it is easer  Set the IsDefault property of the Button relevant to this text-area as true   Once you are done capturing the enter key  do not forget to toggle the properties accordingly

Most beginner friendly solution is    In your Designer  click on the text field you want this to happen   At the properties Window  default  bottom-right  click on the thunderbolt  Events   This icon is next to the alphabetical sort icon and the properties icon  Scroll down to keyDown  Click on the Dropdown field right to it  You ll notice there s nothing in there so simply press enter  Visual Studio will write you the following code   private void yourNameOfTextbox KeyDown object sender  KeyEventArgs e        Then simply paste this between the brackets   if  e KeyCode    Keys Enter         yourNameOfButton PerformClick         This will act as you would have clicked it
