A problem about zIndex.

Dear all:

I wrote a Canvas which has three children.

The third one is on the top, First one is under the second one.

Then, I use a button. When clicking the button,

I remove the third one from the Canvas, and

set the zIndex of first one to 1, second one to 0.

But the first one is still under the second one.

What can I do to let the first one on the top.

BR

Wisenight,

AFIAK the ZIndex affects only the user input, which means the element on the
bottom won't be absured by that is visually on the top with regards to the
mouse input for example. However visually ZIndex doesn't change anything. If
you want to move the control on the top you need to change its position in
the visaul children collection (physically move the element).
