I've got a richtextbox but want to check the keypresses before they come in the textbox. So I thought of using the KeyPress event from the form, checking that key and than writing it to the richtextbox with the Text property.But the KeyChar is a char while the Text property expects a string, and when I convert the KeyChar to a string(ToString) it gives a error.Does anyone know how to fix this or has anyone another idea for checking the presses before writing them?
