1. If you mean that user change Browser size than you cannot know when he stop resize. You can only handle SizeChanged event, like this
private void UserControl_SizeChanged(object sender, SizeChangedEventArgs e)
{
if (e.PreviousSize.Width == 0 || e.PreviousSize.Height == 0)
return;

cmdButton.Width = cmdButton.Width + (e.NewSize.Width - e.PreviousSize.Width);
cmdButton.Height = cmdButton.Height + (e.NewSize.Width - e.PreviousSize.Width);
}

2. If you mean that user change Control size than you can handle MouseLeftButtonDown/MouseLeftButtonUp event, like this:
bool isInResizeMode = false;
Point lastPos;

private void UserControl_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
isInResizeMode = true;
}

private void UserControl_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{
isInResizeMode = false;
}

private void UserControl_MouseMove(object sender, MouseEventArgs e)
{
Point newPos = e.GetPosition(this);

if (isInResizeMode)
{
cmdButton.Width = cmdButton.Width + (newPos.X - lastPos.X);
cmdButton.Height = cmdButton.Height + (newPos.Y - lastPos.Y);
}

lastPos = newPos;
}
