While loading some of the layoutcontrolItem has to be removed from layout control.

Is there any way to remove those?

When i did like this, the control will be in layout and an instance that will bw visible false. how to remove compltely?

Add two line of code after those :

myLayoutControl.Root.Remove(layoutcontrolItem);

layoutcontrolItem.Dispose();

Note: this code does not dispose layoutcontrolItem.Control. Please call the layoutcontrolItem.Control.Dispose method dirrectly if you need it.

 I was told by their support "set its ContentVisible property to false".

Thanks
