Question

I have a multiline textbox on which Ctrl+Enter triggers a specific action. Enter, obviously, creates a new line in the textbox.

Now I would like to invert the two functionalities, i.e. Ctrl+Enter should create a new line and Enter should trigger my specific action. Everything works fine, except where I need to create a new line with Ctrl-Enter.

I tried this solution:
How can I programmatically generate keypress events in C#?
It doesn’t work however, because when I raise a (Preview)Keydown/Up for the Enter key, the Ctrl key is still pressed, so I just end up simulating another Ctrl-Enter on the textbox, which has no effect.

Any help would be appreciated.

This is how I finally simulated an “Enter” on the textbox, even when the Ctrl key is down:

var caretIndex = MyTextBox.CaretIndex;
MyTextBox.Text = MyTextBox.Text.Insert(caretIndex, System.Environment.NewLine);
MyTextBox.CaretIndex = caretIndex + 1;
