Cursor Focus on Textbox in WPF/C#

Question

I am currently in the process of creating a Onscreen keyboard. I am handling the button click using routedcommands. The issue is that when i click on the button in keyboard

Answer 1

Your problem can be solved by using a separate focus scope for your "keyboard". Just apply the following property to the control that contains all of your buttons and then they will be in a separate focus scope and will not have the focus set to them when clicked

FocusManager.IsFocusScope="True"

Answer 2

Get the reference for the specific control(in that case TextBox). After click, in Button_Click method paste this:

Dispatcher.BeginInvoke((ThreadStart)delegate
            {
                control.Focus();
            });

Answer 3

The way I solved this problem was to set focusable=false to all the buttons/controls on the keyboard. That way you don't lose focused of the current control.

Answer 4

Textbox.Focus();

this will focus on the textbox

Answer 5

I had to use this to get my desired result

FocusManager.SetFocusedElement(this, UserNameautoCompleteBox);

Key key = Key.Enter;                    // Key to send
var target = Keyboard.FocusedElement;    // Target element
RoutedEvent routedEvent = Keyboard.KeyDownEvent; // Event to send

target.RaiseEvent(
    new KeyEventArgs(
        Keyboard.PrimaryDevice,
        PresentationSource.FromVisual(UserNameautoCompleteBox),
        0,
        key) { RoutedEvent = routedEvent }
);
