                ctrl is therefore null. So, I assume that means you're setting it with document.getElementById, and not checking the return value. Odds are that you're using the server side ids instead of using the clientId property to get the client side id's for your script.

                    Which browser are you using ? It works fine in IE but firefox. It seems detecting text selection in firefox[^] is different. It may fail because of this reason.

                      Replace first line of show function with below code var ctrl = document.getElementById('<%=FreeTextBox1.ClientID%>'); It might help you.

                          Make sure that your text box control(FreeTextBox1) is enabled and visible. if not then first enable it then set the focus otherwise it gives an error.
