Press enter in textbox to and execute button command

I want to execute the code behind my Search Button by pressing Enter. I have the Accept Button property to my search button. However, when i place my button as NOT visible my search doesn't execute.

I want to be able to press Enter within my text box and execute my button while its not visible. Any suggestions would be great! Below is one attempt at my code in KeyDown Event

if (e.KeyCode == Keys.Enter)
    {
        buttonSearch_Click((object)sender, (EventArgs)e);
    }

private void jobNoToolStripTextBox_KeyPress_1(object sender, KeyPressEventArgs e)
        {
            if(e.KeyChar == Convert.ToChar( Keys.Enter))
            {
                searchJobNo();
            }
        }

sometimes you will have to use the Key Char class, worked the same for me

Since everybody covered the KeyDown answers, how about using the IsDefault on the button?

You can read this tip for a quick howto and what it does: http://www.codeproject.com/Tips/665886/Button-Tip-IsDefault-IsCancel-and-other-usability

Here's an example from the article linked:

<Button IsDefault = "true" 
        Click     = "SaveClicked"
        Content   = "Save"  ... />

There are some cases, when textbox will not handle enter key. I think it may be when you have accept button set on form. In that case, instead of KeyDown event you should use textbox1_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e)

You can handle the keydown event of your TextBox control.

private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
    if(e.KeyCode==Keys.Enter)
    buttonSearch_Click(sender,e);
}

It works even when the button Visible property is set to false

If buttonSearch has no code, and only action is to return dialog result then:

    private void textBox1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Enter)
            DialogResult = DialogResult.OK;
    }

In WPF apps This code working perfectly

private void txt1_KeyDown(object sender, KeyEventArgs e)
  {
     if (Keyboard.IsKeyDown(Key.Enter) )
         {
              Button_Click(this, new RoutedEventArgs());

If you're just gonna click the button when Enter was pressed how about this?

private void textbox1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Enter)
        {
            buttonSearch.PerformClick();
        }

Alternatively, you could set the .AcceptButton property of your form. Enter will automcatically create a click event.

this.AcceptButton = this.buttonSearch;

You could register to the KeyDown-Event of the Textbox, look if the pressed key is Enter and then execute the EventHandler of the button:

private void buttonTest_Click(object sender, EventArgs e)
{
    MessageBox.Show("Hello World");
}

private void textBoxTest_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Enter)
    {
        buttonTest_Click(this, new EventArgs());
    }
}
