Hi,
I want a checkbox in such a way that if it is uncheck the user can check it.
but if it is checked the user should not be able to uncheck it .
can anyone please help.

Can you use JavaScript on this?
You can use the OnClick event of the checkbox item.. like

onclick="javascript:this.checked=true;"
