Is it possible to display the 'x' for the html flag when we click on it. Traditionally on i.e. (On winxp and above) it is displayed as a tick sign. Can we change this? Or what is an alternative to this in asp.net
I think you can hack something using images instead of a real checkbox using javascript to change the image selection
I'm not sure if you are talking to a web application or a windows application. Suppose you had in mind a web application. You cannot change the normal input, it is something in the system settings.
