Set focus on a textbox control in UserControl in wpf

Question

I have created an UserControl which is loaded in a View (Window) in WPF. In my user control I have put a TextBox. I am unable to set focus on this

Answer 1

Register the Loaded-Event of your UserControl and set the Focus on your PwdBox by calling Focus() when your UserControl is loaded.

public class MyUserControl : UserControl{

  public MyUserControl(){
    this.Loaded += Loaded;
  }

  public void Loaded(object sender, RoutedEventArgs e){
    PwdBox.Focus();
    // or FocusManager.FocusedElement = PwdBox;
  }
}
