Problem with check box?

Hi All,

As per the requirement, I have a view and in that I have to have a check box.

In the same view I have a button. On click of that I have to display a popup with three drop downs.

So, if the check box is checked, then one of the three drop downsin the popup should be disabled. if not then when the button is clicked the the popup should come with all the drop downs enabled.

I have taken check box by key. I have assigned to the checked property of the check box UI element a boolean value.

And to the toggle action i have got an event handler also.

But I am nt able to set the drop down disabled and enabled.

So if any one of you can let ma the correct approach with code snippet the it will be relly appreciable.

Regards

DK
