I have one asp.net application, in which i have to disable or make it as read only to the Paste option from the context menu. But i searched in internet. I didn’t get one exact method. Please help me for resolve this issue. Thanks in advance
The short answer is that you can’t do this.
The user’s browser is their own, and as such they have the sovereign power to interact with your page however they want. You can catch right-click events to prevent the menu from coming up; you can catch keypress events to stop Ctrl-V (and Shift-Insert, which is often forgotten) from being registered. However, you can’t remove the Edit -> Paste menu option, which works within the browser and subverts Javascript altogether.
Not to mention that the user could just disable Javascript temporarily, paste into the field, then reenable Javascript if they wanted.
Even if you’re happy with the limitations, you cannot modify the actual context menu, only prevent the right click from registering at all.
