Hi All

In my application, i have a listbox and a checkbox

What i am doing is, when the chekbox is cheked, all items in listbox are selected.

When unchecked, all items are deselcted.

Upto this, it s workng..

But now, suppose the checkbox is checked, and all the itms are selected, the user selects a particlar item from the listbox, all the other items get deselected.

But the checkbox remains checked.

I am confused how to make the checkbox unchecked, when any itmes in the listbox are selected??
I read that i can write javascript on listbox clcik event, but i dont know javascript. if someone can help in this it will reallly gretaful

Hope someone can suggest any ways to accomplish this

Thanks

Javascript is the way to go as its pointless to make another round trip to the server in this case. A simple google search on forms validation should get you the code you need.
