Enter key pressed event handler

Question

I want to capture the text from the textbox when enter key is hit. I am using WPF/visual studio 2010/.NET 4. I dont know what event handler to be used in the tag ? I also want to do the same for maskedtextbox.

Answer 1

Either KeyDown or KeyUp.

TextBox tb = new TextBox(); tb.KeyDown += new KeyEventHandler(tb_KeyDown);  static void tb_KeyDown(object sender, KeyEventArgs e) {     if (e.KeyCode == Keys.Enter)     {         //enter key is down     } } 

Answer 2

You can also use PreviewKeyDown in WPF:

<TextBox PreviewKeyDown="EnterClicked" /> 

or in C#:

myTextBox.PreviewKeyDown += EnterClicked; 

And then in the attached class:

void EnterClicked(object sender, KeyEventArgs e) {     if(e.Key == Key.Return) {         DoSomething();         e.Handled = true;     } }
