Crazyjh,

For using dynamic controls it is important to know if it is about a webpage
or a winform. They act completely different in this, so let us know that to
make the answers not only confusing.

Crazyjh,

The oposite from adding a control is the control.remove

I hope this helps,

You can remove the control from the container's (form, control) 'Controls'
collection.

crazyjh,

You have to remove the original added control. This lbl(i) is a complete new
label that is never in your control collection as long as you don't add it.

You can as well use the removeAt.

Be aware that this reindexes the index.
