Question

In WindowsForms i use this samlpe code:

textBox.Paste("some text");

Is there a TextBox method with the same function in WPF?
Or there is a nice workaround?

Answer 1

    public static void Paste(this TextBox textbox, string textToInsert)
    {
        int caretIndex = textbox.CaretIndex;
        string textBoxContent;

        if (textbox.SelectedText.Length > 0)
        {
            textBoxContent = textbox.Text.Remove(caretIndex, textbox.SelectedText.Length);
        }
        else
        {
            textBoxContent = textbox.Text;
        }

        textbox.Text = textBoxContent.Insert(caretIndex, textToInsert);
        textbox.CaretIndex = caretIndex + textToInsert.Length;
    }
