I am using radtextbox in aspx page. I have a web service and it returns a string. I want to add these string to my textbox permanently. So when somebody click on my radtextbox they can't delete these string which already in textbox but they add characters on it. How can I do that?
One suggestion is that you can use a span and on that set the permanent value of the RadTextBox and place it inside the RadTextBox. So it is not possible to delete the permanent text and can add more text to it. Please have a look into the following sample code snippet.
